Traditional villages represent a concentrated expression of the preservation and transmission of traditional culture within the context of rural revitalization,conveying important social,historical,and cultural values.Based on the perspective of spatial genes,this study selected 67 typical traditional villages in the Wuling Mountain Area in Southwest China as the case study.Between 2021 and 2024,by identifying and extracting spatial genes through the semi-structured interviews,Laddering Technique,and Landscape Pattern Index,and applying the geo-detector,the study explored the morphological characteristics and influencing mechanisms of traditional Tujia villages from the perspective of spatial genes of ecological-production-living.The findings are as follows:1)the spatial genes of traditional Tujia villages in the Wuling Mountain Area exhibit distinct patterns.Ecological genes,categorized by natural environment and layout,demonstrate a transition from clustered to dispersed patterns from the southern to northern regions.Production genes,categorized by location and cultivation patterns,show concentrated agricultural lands in the south and fragmented in the north.Living genes,divided into house plans,facades,and public buildings,reveal a higher prevalence of courtyards,stilted houses,and public buildings in northern areas.2)The spatial genes have evolved through the combined influence of four key factors:natural environment,socioeconomic development,policy systems,and ethnic culture.3)The integration of multi-source data and the application of both qualitative and quantitative approaches provide a comprehensive framework for analyzing traditional village form and their influencing mechanisms.This methodology offers valuable insights for developing sustainable strategies for the conservation of traditional Tujia traditional villages in this region. 展开更多

Understanding how ecological engineering influences the trade-offs and synergies among regional ecosystem services can provide valuable insights for enhancing ecosystem functionality and promoting a virtuous and sustainable ecological cycle.This study focuses on the Changbai Mountain region,a key ecological conservation area in northeastern China.It employs global spatial autocorrelation analysis and bivariate spatial correlation methods to explore the spatial patterns of five key ecosystem services—soil retention,carbon sequestration,water purification,habitat quality,and water yield—as well as the spatial heterogeneity of the trade-offs and synergies among them.The results indicate that:(1)Forest land is the dominant land-use type in the study area,with land-use changes primarily occurring among grassland,forest,and cropland.(2)The implementation of the“Mountain-River Project”has significantly enhanced ecosystem service capacities.Specifically,the average habitat quality has remained stable at 0.97;average water yield increased from 716 mm to 743 mm;average nitrogen purification rose from 0.025 to 0.028;and total soil retention increased from 8.7×107tons to 5.09×108tons.(3)Synergistic relationships dominate the interactions among individual ecosystem services in the Changbai Mountain region.The implementation of ecological engineering has further strengthened synergies—particularly among soil retention,water yield,and other services.However,the short-term impacts of the project have somewhat weakened the synergies between water purification and other ecosystem services.These findings offer a novel perspective for understanding the effects of ecological engineering on ecosystem services and provide a scientific basis for future ecological restoration planning and management. 展开更多

Alterations in treeline ecotones within mountain ecosystems are widely recognized as sensitive indicators of climate change.This study investigates treeline dynamics in the Ilgaz Mountain region,Türkiye,over a 23-year period(2000-2023)by integrating high-resolution satellite imagery with longterm meteorological data.Treeline elevations were analyzed across different slope aspects to assess spatially heterogeneous responses to climatic variability.Our results reveal a statistically significant upward shift in the treeline on south-facing slopes,with the mean treeline elevation increasing from 2021 m to 2032 m(p<0.05),while no significant shifts were detected on other aspects.Long-term climatic analyses indicate pronounced warming in the study area,with mean annual temperature increasing by approximately 1℃,particularly after 2010.Mann-Kendall trend analysis confirms a strong,significant positive temperature trend(τ=0.522,p<0.001).In contrast,annual precipitation shows no significant temporal trend(τ=0.138,p=0.36).Similarly,the De Martonne aridity index does not exhibit a statistically significant directional trend,although index values suggest a gradual transition from very humid to humid conditions at the treeline ecotone.The observed aspect-specific response to warming underscores the importance of local microclimatic and topographic controls in mediating treeline sensitivity to climate change,even over relatively short time periods.Overall,this study demonstrates the utility of high-resolution remote sensing techniques for delineating treeline boundaries and detecting landscape-scale changes in complex mountain environments. 展开更多

Climate change,land use/cover changes(LUCC),and landscape pattern alterations have increasingly complicated interactions among ecosystem services(ES)in temperate mountain forests,underscoring the importance of understanding the mechanisms underlying the dominant trade-offs and synergies to inform sustainable natural resource management.In this study,we quantified the degree of trade-offs and synergies among water yield(WY),soil retention(SR),carbon storage(CS),and habitat quality(HQ),and elucidated their dominant drivers in the Changbai Mountain Region,Northeast China,from 1990 to 2020.Our results demonstrated that SR(+29.56%)and CS(+9.90%)increased,while WY(−8.77%)and HQ(−20.77%)decreased over the 30 years.ES interactions were dominated by trade-offs between WY and SR and synergies between WY and HQ.These dominant interactions were mainly driven by LUCC,particularly cropland expansion,forest loss,and urbanization,along with landscape pattern alterations associated with increased fragmentation and enhanced connectivity from afforestation,whereas climatic changes played a comparatively smaller role.LUCC not only directly influenced ES interactions but also exerted indirect effects through its alterations of landscape patterns.These complex,multifaceted drivers shape ES relationships and intensify mismatches between ES supply and demand,underscoring the urgent need for integrated,spatially explicit management strategies to balance ES provisioning and ensure long-term ecological sustainability in montane regions. 展开更多

Understanding the mechanisms driving species assembly along elevational gradients in mountains is crucial for biodiversity conservation.However,no consensus has yet been reached on how these mechanisms work.This knowledge gap is particularly pronounced in biodiversity-rich subtropical karst mountains.Integrating multidimensional biodiversity information into research in karst systems will provide new insights into community assembly.Thus,we explored multidimensional forest diversity along an elevational gradient at Jinfo mountain,a karst mountain site,assessing the relative importance of distinct ecological processes in shaping patterns of community diversity and structure.Our results show that different dimensional diversities exhibit similar elevational patterns,with higher diversity observed at low-to-mid elevations than at high elevations.The multidimensional diversity and structure were primarily controlled by climate stress and topographic filtering and were further modulated by soil nutrient limitation and interspecific competition.However,the explanatory weights of these ecological processes were inconsistent among the different dimensions of diversity.The phylogenetic structure was clustered at low and middle elevations,with over-dispersion at high elevations.This indicates that community assembly shifted from being dominated by environmental filtering to being dominated by competitive exclusion as elevation increased.In conclusion,our results demonstrate that combining multidimensional diversity and multiple ecological processes related to community assembly can enhance the understanding of diversity patterns along elevational gradients and the underlying mechanisms maintaining them in subtropical karst mountains. 展开更多

As a critical ecological barrier in China,the Qinling Mountains see their ecological functions significantly impaired by frequent shallow landslides.However,existing research on the distribution characteristics and driving mechanisms of such landslides remains relatively limited.To address this knowledge gap,the present study integrated data analysis,field investigations,and remote sensing interpretation to construct a landslide database for the core area of the Qinling Mountains,and systematically analyzed the spatial patterns,development characteristics,and environmental driving factors of shallow landslides.The results reveal that shallow landslides are predominantly small-to-medium in scale,concentrated in regions with an altitude of 800–1000 m and a slope gradient of approximately 30°,with a distinct tendency to develop on sunny(southfacing)slopes.The occurrence frequency of these landslides exhibits a significant positive correlation with the soil moisture content of the weathered layer and the degree of groundwater enrichment in the study area.Specifically,these landslides are mainly developed in bedrock fissure water zones and karst fissure water zones with favorable water-bearing capacity,indicating that rainfall and surface hydrological processes are the key triggering factors for shallow landslides.Notably,vegetation exerts a mediating role in the"vegetation-hydrology-landslide"system:shallow landslides occur most frequently in areas with artificial or shrub-grass vegetation,peaking at a moderate coverage of 50%–60%.This peak suggests that vegetation within this range is ineffective at regulating soil moisture,while the interaction between specific vegetation types and hydrological enrichment further exacerbates landslide risk.By prioritizing the weights of vegetation and hydrological factors,we enhanced the information quantity model,which significantly improved its performance and increased the AUC value to 0.83.These findings confirm the pivotal roles of vegetation and hydrological factors,thereby providing a robust scientific basis for targeted landslide prevention and control in this region. 展开更多

Global climate change is intensifying the impact of slope hazards,particularly rainfall-induced landslide hazards(RILH),on mountain road networks(MRNs).However,effective quantitative models for dynamically assessing MRNs vulnerability under RILH disturbances are still lacking.To bridge this gap,this study develops a Cascading Failure Model for Rainfall-Induced Landslide Hazard(CFM-RILH).Validation via a case study of the GarzêTibetan Autonomous Prefecture Road Network(GTPRNs)reveals key characteristics of MRNs system vulnerability under RILH disturbances:(1)Under the disturbance effects of RILH,the vulnerability of the MRNs system follows a nonlinear phase transition law that intensifies with increasing disturbance intensity,exhibiting a distinct critical threshold.When the disturbance intensity exceeds this threshold,the system undergoes a global cascading failure phenomenon analogous to an“avalanche.”(2)Under RILH disturbances,the robustness of the MRNs system possesses a distinct safety boundary.Exceeding this boundary not only fails to improve hazard resistance but instead substantially elevates the risk of large-scale cascading failure.(3)Increasing network redundancy may be considered one of the primary engineering measures for enhancing MRNs resilience against such disturbances.Based on these findings,we propose a“Two-Stage Emergency Response and Hierarchical Fortification”strategy specifically to improve the resilience of GTPRNs impacted by RILH.The CFM-RILH model provides an effective tool for assessing road network vulnerability under such hazards.Furthermore,its modeling framework can also inform vulnerability assessment and resilience strategy development for road networks affected by other types of slope hazards. 展开更多

Global climate change has intensified the frequency and severity of extreme rainfall events,thereby exacerbating flood disasters.To mitigate such risks,timely and accurate rainfall measurements are essential,yet cost-effectiveness must also be considered.However,many river basins—particularly mountainous small watersheds—suffer from poorly designed rain gauge networks,limiting real-time data acquisition.Existing optimization methods are largely developed for large river basins or plains and are not directly applicable to mountainous small watersheds,where rainfall exhibits strong spatial heterogeneity and gauge networks are sparse.To address this gap,this study takes the Fuhuxi Watershed of Mount Emei in Sichuan Province,Southwest China,as a case study and develops a collaborative optimization framework integrating information entropy,the Maximum Information Minimum Redundancy(MIMR)criterion,and Long Short-Term Memory(LSTM)networks.Specifically,we quantified the information entropy matrix of seven existing rain gauge stations and applied the MIMR criterion,resulting in the retention of five key stations.The optimized network preserves 99%of the effective rainfall information from the original seven stations while significantly reducing operational and maintenance costs.Using data from nine rainfall-induced flood events between 2018 and 2023,we developed an LSTM-based runoff simulation model.The optimized network,which removes stations with low information content and high redundancy,achieved excellent flood simulation accuracy.The study demonstrates that:(1)information entropy theory effectively interprets the spatial correlation and information redundancy of rain gauge stations in mountainous small watersheds;and(2)the LSTM model validates the feasibility of using an optimized rain gauge network to support highprecision flood simulations.Finally,we propose suggestions for future research,particularly regarding the optimization of rain gauge networks to improve the understanding of optimal network design and thereby enhance the accuracy of rainfall-runoff simulations. 展开更多

Tunnel portal sections have historically been more susceptible to earthquakes than other components,exhibiting significant seismic damage.However,critical seismic behaviors of portal sections remain unrevealed owing to insufficient consideration of actual topography.Moreover,the extent of asymmetric seismic responses induced by topography remains unclear,which is essential for seismic design.To overcome these limitations,this study replicated the actual geological conditions of a tunnel portal section,including the portal slope,topography,slope and tunnel supports,and the often-overlooked portal wall using large-scale shaking table tests.The asymmetric seismic responses and their impact ranges identified in the experiments were validated through numerical simulations.The results revealed that the seismic damage to the slope is attributable to the presence of the tunnel,with slope acceleration near the tunnel portal increasing by 20%–40%compared to slopes without a tunnel.Additionally,the tunnel facilitates seismic wave propagation in specific directions,leading to further seismic damage across the portal section.Portal walls,being exposed structures,are susceptible to higher seismic strain and acceleration than tunnel linings and thus warrant increased attention.Importantly,the asymmetric seismic response was found to vary based on different sides and influence ranges.Within 15 m of the portal,the tunnel was dominated by the open-side asymmetric response of acceleration,strain,and displacement.From 15 to 35 m range,the seismic response of the mountainside was more pronounced,exhibiting increased seismic earth pressure and stress on the right sidewall.Seismic earth pressure and stress diminished within the 35–75 m range and steadily decreased beyond 75 m.This enhanced understanding of seismic behaviors facilitates the targeted establishment of future seismic fortifications based on these classified ranges. 展开更多

Objective Stress-induced changes in echocardiographic parameters reflect cardiac reserve function.This study aimed to identify predictors of acute mountain sickness(AMS)using exercise stress echocardiography(ESE)before ascent.Methods In this prospective cohort study,104 healthy adults were enrolled and treated using ESE using a mechanically braked bicycle ergometer at a low altitude(LA)(500 m).Physiological data and echocardiographic parameters were collected before and during exercise.An ascent from 500 m to 4,100 m was completed by the bus within two days.AMS was identified using the Lake Louise Questionnaire.Results Among the 104 participants,49 developed AMS at 4,100 m.Compared with individuals without AMS,those with AMS had a higher low-altitude(500 m)heart rate(HR)but lower stroke volume(SV)at rest,lower cardiac output(CO)and SV during exercise,and lower rates of change in CO,SV,and HR.Multivariate regression analysis revealed that female sex(odds ratio[OR]=3.17,P=0.039)and the rate of change in CO during exercise(OR=0.98,P=0.001)were independent risk factors for AMS.Participants with the lowest CO change rate after ESE presented the highest AMS risk.Conclusion ESE could serve as an effective screening tool for AMS susceptibility,and blunted CO augmentation during exercise is an independent predictive marker for AMS risk. 展开更多

Polycyclic aromatic hydrocarbons(PAHs)constitute a significant class of environmental hazards in the atmosphere,posing considerable risks to human health owing to their mutagenic,carcinogenic,and persistent nature.Although some studies have focused on PAHs in human-impacted areas,the characteristics and sources of PAHs in remote regions,such as high-altitude atmospheres,remain to be clarified.During the summer of 2021,we conducted intensive field measurements at the summit of Changbai Mountain(2623 m above sea level),the highest peak in Northeast Asia.Eighteen PAH species were detected in the collected PM₂.₅samples,and their chemical compositions,temporal variations,long-range transport,and associated health risks were analyzed.The average PAH concentrations were 0.92±0.36 ng/m³,dominated by compounds containing 2–3 and 5–7 aromatic rings.Backward trajectory analysis underscored the influence of long-range transport on PAH levels at Changbai Mountain,with the air masses originating from the Korean Peninsula characterized by high PAH concentrations.Major sources of PAHs included biomass and coal combustion,vehicle emissions,and oil/gas/petroleum and diagenetic processes.The estimated health risks were below the threshold set by the World Health Organization,indicating minimal carcinogenic risk from atmospheric PAHs at Changbai Mountain.Although this study was conducted only during the summer season,it establishes critical baseline data on transboundary PAH transport patterns in Northeast Asia.These findings provide valuable insights into the long-range transport,sources,and potential health risks of environmental hazards in Northeast Asian regional background atmosphere,and highlighting the necessity for future investigations encompassing seasonal cycle dynamics. 展开更多

Mountain soil organic carbon(SOC)is a key component of the global carbon cycle,yet research on its elevational controls has expanded rapidly without a clear synthesis of knowledge structure and emerging frontiers.Here,we conduct a bibliometric analysis of1,391 Web of Science publications(1995–2025)to map the intellectual base,research hotspots,and temporal evolution of SOC studies along elevational gradients.Co-citation and keyword analyses reveal a clear transition from descriptive assessments of SOC stocks toward mechanism-oriented investigations that link SOC dynamics to elevation-structured processes.Prominent thematic clusters include“altitudinal gradient,”“vegetation degradation,”and“microbial necromass carbon,”highlighting increasing attention to biotic regulation and stabilization pathways.Across mountain systems,SOC exhibits diverse elevational patterns and strong within-elevation heterogeneity,reflecting the combined influence of climate constraints,vegetation-mediated carbon inputs,soil physicochemical environments,and microtopography(e.g.,aspect and slope position).Building on these trends,we identify priorities for future research,including cross-region comparisons using standardized designs,integrated frameworks connecting vegetation–microbial processing with mineral/aggregate protection,explicit consideration of alpine and cryosphere dynamics,and the use of remote sensing and GIS to upscale SOC monitoring and modeling in complex terrain. 展开更多

The Qilian Mountains(QLMs),a critical transitional zone between China's cold and arid regions,serve as a vital ecological security barrier and water conservation area.Their sustainable development is essential for achieving regional ecological civilization and coordinated socio-economic progress.This study,grounded in ecological carrying capacity theory,established a comprehensive evaluation index system for the QLMs,delineated ecological functional zones using natural and socioeconomic data from 2001–2020,and then explored six sustainable development modes.Results revealed significant spatial heterogeneity in ecological carrying capacity in QLMs from 2001 to 2020,based on which ecological red line(32.02%),yellow line(40.30%),and green line(27.68%)zones were designated.The red,yellow,and green line zones correspond to priority conservation,conservation-development coordination,and appropriate development areas,respectively.For different zones,six differentiated development modes were proposed,the ecological conservation mode emphasized strict protection and systematic restoration to secure key ecological functions.The ecological compensation mode used institutionalized compensation to offset conservation costs and improve both protection performance and livelihoods.The ecological tourism mode leveraged natural and cultural resources to generate green income.The aboriginal integration mode strengthened resilience through livelihood transition and cultural continuity.The community co-management mode enhanced local governance through shared rights,responsibilities,and benefits.The social participation mode reinforced regional governance via multi-actor collaboration and resource integration.Overall,ecological red line zones emphasized conservation and compensation,yellow line zones balanced social participation,while green line zones integrated all six modes.This study provided actionable solutions to resolve the conflict between ecological protection and economic development in the QLMs,and offered a replicable‘assessment-zoning-modeling'framework for sustainable development in other ecologically fragile and barrier regions in China. 展开更多

Research on grassland ecological compensation is highly significant for promoting grassland ecosystem protection and realizing sustainable development of regional animal husbandry.Herdsmen's satisfaction with the grassland ecological compensation policy has,to a certain extent,improved the compensation policy and performance.A total of 197 herdsmen were selected from three typical pastoral areas in the Qilian Mountains:Maozang Township,Huangcheng Town,and Yeniugou Township.Combined with questionnaire surveys and in-depth interviews,an ordered logistic model was constructed to analyze the influence of relevant factors on satisfaction.The results indicate that 45.1%of the surveyed herdsmen are"relatively satisfied"and"very satisfied"with the compensation policy.Actual inventory,changes in household income,and their agreement to ecological migration have significantly negative impacts on the satisfaction of the surveyed herdsmen,while gender,age,contracted grassland area,and changes in employability indicate no significant impact.To effectively implement the grassland policy and improve the livelihood of herdsmen,it is necessary to accelerate the perfection of the mechanism design of the grassland ecological compensation policy and formulate differentiated grassland ecological compensation standards. 展开更多

The man-land relationship and its dynamics were core themes in modern geography.Complex interactions exist between the natural environment and human activities.However,current research focused on the impacts of human activities on ecosystems,ignoring the linear or non-linear characteristics and interaction thresholds.In this study,multi-source data and self-organizing feature map(SOFM)were used to classify man-land relationship areal types in southern Shaanxi,China from 2000 to 2020.The constrain lines method was employed to identify the interaction thresholds between human activities intensity(HAI)and various natural indicators.Results showed that:1)higher and high natural environment index(NEI)accounted for more than 75%of the southern Shaanxi.2)Low and lower HAI covered over 85%of the total area,with significant decreases and significant increases in HAI occurring in 45.61%and 24.53%of the study area,respectively.3)The agricultural type decreased in southern Shaanxi,while the urban and comprehensive type increased.4)There was a negative convex relationship between HAI and NEI.Thresholds for the effect of HAI on habitat quality were 0.67,0.37,and 0.64 in the Qinling Mountains,Hanjiang Basin and Daba Mountains,respectively.This study emphasizes that one or more thresholds should be considered for ecological restoration and human management in different regions,and provides a new perspective for understanding the complex man-land relationship in underdeveloped mountainous regions and offered strong support for coordinating ecological protection with socio-economic development. 展开更多

The upper forest boundary in the mountains is a reliable bioindicator of modern climate change,though its dynamics are influenced by multiple factors.Conjugate studies on the structure of tree stands and the soil properties across the elevation gradient were performed at the treeline on slopes of different exposures in the Altai Mountains.The oldest trees on the northern slope were established in the mid-15th century,but intensive expansion began in the 20th century,whereas tree establishment on the eastern slope began later and occurred over a shorter period.A significant positive correlation was revealed between summer and winter temperatures,winter precipitation,and the rate of Pinus sibiricaestablishment.The open forest boundary reaches its highest elevation on the eastern slope,where conditions are intermediate between the northern and southern slopes in terms of snow cover duration and land surface temperature.The differences in soil types reflect the contrasting conditions influenced by slope exposure.The earlier colonisation of northern slopes has led to the formation of typical forest soils(Skeletic Podzols)at higher elevations under open forest stands.These soils are more acidic,with slower litter decomposition and pronounced accumulation of carbon and nutrients in their organic surface horizons,while their mineral horizons are nutrient-poor.In contrast,soil at the eastern slope(Folic Leptosols)has a higher element content throughout the soil profile and displays minimal disparities and variation in the morphology and chemistry across the treeline ecotone.The mismatch transition between vegetation and soil belts suggests that soil properties respond to climatic changes more slowly than vegetation dynamics. 展开更多

Numerous economically underdeveloped and ecologically fragile areas in southern China's mountainous regions face increasing challenges in achieving sustainable development. A comparative analysis of ecosystem service responses to land use scenarios, incorporating adaptive valuation coefficients, can reveal actionable pathways to reconcile sustainable development and ecological conservation in mountainous regions. In this study, the ecosystem service value(ESV) dynamics in the Hunan–Jiangxi Border Region(HJBR), which is a representative old revolutionary base with a relatively undeveloped economy, were investigated by integrating historical land use data analysis from 2000 to 2020 and adopting patch-generating land use simulation(PLUS) modelling. Three policy-responsive scenarios, namely, natural growth(NGS), farmland protection(FPS), and ecological protection(EPS), were systematically developed to project ESV variations for 2030 and 2040. Our analysis revealed that from 2000 to 2020, urban sprawl and water body expansion occurred at the expense of forestland, cultivated land, and grassland, yet yield-driven productivity improvements increased the ESV by 227.30%(equivalent to ¥250.0 billion). By 2040, the NGS achieves the greatest ESV increase(¥189.895 billion) while fully accommodating urban land demand;the FPS yields the smallest ESV increase(¥148.169 billion), with the EPS occupying an intermediate position(¥182.207 billion). Climate regulation and hydrological services dominate ecological functions, collectively exceeding 49% across all the scenarios and periods. By 2040, most service functions exhibit growth trends except for a 0.30% water supply decline under the FPS, whereas the EPS demonstrates balanced development through multidimensional service enhancements. These findings underscore the necessity of integrating ecological safeguards into land use planning frameworks to ensure sustainable regional development. 展开更多

The Qilian Mountains(QLM)are characterized by their ecological fragility and environmental sensitivity.Vegetation,the dominant ecosystem in this region,plays a crucial role in water conservation,climate regulation and biodiversity protection.Based on fractional vegetation cover(FVC)data,this study employed trend analysis,Pearson correlation analysis,and PLS-PM(Partial Least Squares Path Modeling,PLS-PM)methods to investigate the current distribution characteristics of vegetation in the QLM in 2023 from the perspectives of annual and intra-annual variations,with a detailed exploration of its latitudinal zonality and regional differentiation patterns.Additionally,the spatiotemporal trends of vegetation changes in the QLM from 2000 to 2023 were analyzed,and the contributions of various influencing factors to vegetation dynamics were assessed both qualitatively and quantitatively.The results indicated that:(1)In 2023,the FVC in the QLM exhibited a pattern of lower values in the northwest and higher values in the southeast,with overall vegetation coverage being relatively low.The Huangshui River Basin(HB)had the highest mean FVC at 0.51,while the Haerteng River Basin(HETRB)had the lowest mean FVC at 0.05.Mean FVC decreased with elevation,peaking in the 2,500–3,000 m altitude range.The 98-E longitude line served as a distinct boundary,with more abundant vegetation coverage in the east than in the west.Higher monthly mean FVC values was observed between June and October.Vertical zonal differences in FVC distribution across different basins were significant,with the maximum FVC value of 0.96 observed in July within the 3,000–3,500 m elevation range of the HB.(2)From 2000 to 2023,vegetation in the QLM showed an increasing trend,with the rate of increase fluctuating with elevation and exhibiting upward fluctuations with increasing longitude.Significant differences in vegetation change rates were observed across different basins.The Shiyang River Basin(SYRB)had the highest average annual FVC increase rate at 0.40%,while the HETRB and the Yuka-Tataleng River Basin(YKTTLRB)had the lowest rates at 0.13%.The average FVC change rate demonstrated a significant increasing trend from May to October.(3)Climate remained the primary driver of vegetation growth,exerting a significant direct effect on FVC with a coefficient of 0.9072.Among climatic factors,actual evapotranspiration and precipitation were identified as the dominant influences on vegetation change in the QLM.Altitude and solar radiation had negative feedback effects on FVC,with coefficients of-0.0090 and-0.2244,respectively.Among all factors,climate exhibited a significant total effect(0.6125)on human activities. 展开更多

High-elevation forests are among the most climate-sensitive ecosystems,and understanding their growth responses is crucial for predicting ecological consequences under future climate change.The climate sensitivity of tree species in the Hyrcanian forests in the Alborz Mountains of northern Iran,one of the southernmost temperate deciduous forests in the Northern Hemisphere,remains largely unexplored.In particular,Acer hyrcanum Fisch.&C.A.Mey.,growing mainly at high elevations,has not yet been studied in detail in dendroclimatology.Here,we present the first tree-ring chronology of Acer hyrcanum spanning 1814-2022 and analyze its growth-climate relationships to assess how this species reflects climatic sensitivity at the upper forest limit.The results reveal significant positive correlations between tree-ring width and temperature,particularly from May to September,suggesting that warmer growing-season temperatures enhance tree growth.In contrast,tree-ring width showed negative correlations with precipitation and standardized precipitation-evapotranspiration index,especially from January to May,and with cloud cover from March to May.These findings suggest that moisture availability does not limit radial growth in Acer hyrcanum and that the precipitation and water surplus signals may instead reflect the influence of cloud cover,which reduces sunlight availability during critical early-season months.This study contributes to the growing body of dendroclimatic research in the Alborz Mountains and,more broadly,on Acer species,particularly in high-elevation ecosystems where such studies are scarce.It also provides valuable insights into how Acer hyrcanum may respond to future climate change. 展开更多
