Rural domestic sewage treatment is critical for environmental protection.This study defines the spatial pattern of villages from the perspective of rural sewage treatment and develops an integrated decision-making system to propose a sewage treatment mode and scheme suitable for local conditions.By considering the village spatial layout and terrain factors,a decision tree model of residential density and terrain type was constructed with accuracies of 76.47%and 96.00%,respectively.Combined with binary classification probability unit regression,an appropriate sewage treatment mode for the village was determined with 87.00%accuracy.The Analytic Hierarchy Process(AHP),combined with the Technique for Order Preference(TOPSIS)by Similarity to an Ideal Solution model,formed the basis for optimal treatment process selection under different emission standards.Verification was conducted in 542 villages across three counties of the Inner Mongolia Autonomous Region,focusing on the standard effluent effect(0.3773),low investment cost(0.3196),and high standard effluent effect(0.5115)to determine the best treatment process for the same emission standard under different needs.The annual environmental and carbon emission benefits of sewage treatment in these villages were estimated.This model matches village density,geographic feature,and social development level,and provides scientific support and a theoretical basis for rural sewage treatment decision-making. 展开更多

Flash droughts(FDs)develop quickly and can rapidly deplete soil moisture,posing significant threats to agriculture and pastoral systems.To investigate the spatiotemporal characteristics and development mechanisms of FDs in Inner Mongolia,China,and to assess the roles of key meteorological drivers in driving soil moisture variability,FD events were identified using root-zone soil moisture data during the growing seasons from 1982 to 2022.The results indicate the presence of five FD hotspot regions,located in the southern Alxa Plateau,the Hetao Plain in Bayannur,the northwestern Xilingol Plain,the western Liaohe River Plain,and the northern Da Hinggan Ling.Over 41 years,FDs occurred on average 7.44 events across the study area,with a mean duration of 9.17 pentads(1 pentad equals 5 days).The duration exhibited a significant increasing trend of 0.39 pentads/10 years.FD onsets primarily lasted for 2-3 pentads.During the FD development phase,precipitation and evapotranspiration decreased while temperature,potential evapotranspiration,incoming solar radiation,and vapor pressure deficit increased.The dominant meteorological drivers of FD development exhibited notable spatial heterogeneity across hotspot regions,and vapor pressure deficit consistently was the most influential factor.These findings improve the understanding of climate drivers at different stages of FD development and provide scientific support for early warning and prevention of droughts in Inner Mongolia. 展开更多

This study investigates climate-and human-induced hydrological changes in the Zavkhan River-Khyargas Lake Basin,a highly sensitive arid and semi-arid region of Central Asia.Using Mann-Kendall,innovative trend analysis,and Sen's slope estimation methods,historical climate trends(1980-2100)were analyzed,while land cover changes represented human impacts.Future projections were simulated using the MIROC model with Shared Socioeconomic Pathways(SSPs)and the Tank model.Results show that during the past 40 years,air temperature significantly increased(Z=3.93***),while precipitation(Z=-1.54*)and river flow(Z=-1.73*)both declined.The Khyargas Lake water level dropped markedly(Z=-5.57***).Land cover analysis reveals expanded cropland and impervious areas due to human activity.Under the SSP1.26 scenario,which assumes minimal climate change,air temperature is projected to rise by 2.0℃,precipitation by 21.8 mm,and river discharge by 1.61 m3/s between 2000 and 2100.These findings indicate that both global warming and intensified land use have substantially altered hydrological and climatic processes in the basin,highlighting the vulnerability of western Mongolia's water resources to combined climatic and anthropogenic influence. 展开更多

High-Mg andesite/diorite(HMA)is useful for identifying subduction-related processes in orogenic belts,including the identification of ophiolites formed in suprasubduction zone(SSZ)environments.The E'rentaolegai high-Mg diorite from the Diyanmiao ophiolite in central Inner Mongolia,North China,has been investigated revealing low-K tholeiitic-calc-alkaline characteristics and have SiO2contents of 53.44-54.92 wt%,MgO contents of 8.44-9.54 wt%,and Mg~#of 54.35-57.60,with variable Fe2O3(7.51-8.61 wt%),Al2O3(11.95-15.09 wt%),and Na2O(3.42-3.94 wt%)contents,low K2O(0.34-0.97 wt%),TiO2(0.35-0.67 wt%),and P2O5(0.12-0.15 wt%)contents,and high Ni(43-193 ppm)and Cr(189-556 ppm)contents.Samples collected have low total rare earth element(REE)contents(30.58-77.80 ppm),with flat or slightly right-dipping REE patterns(LaN/YbN=2.19-3.11)and a lack of pronounced Eu anomalies.The samples are also enriched in large-ion lithophile elements(LILEs,e.g.,K,Rb,Ba,U,and Sr)and depleted in high field strength elements(e.g.,Ta,Nb,Ti,and P).The E'rentaolegai high-Mg diorite has characteristics typical of HMA,and are similar to those of sanukites from the Setouchi Arc in SW Japan.They also display high positiveεNd(t)values(+6.32 to+7.80),comparable to the values of their host rocks.Petrogenetic analyses suggest that the E'rentaolegai HMA was probably formed by the interaction of partial melts and aqueous fluids from subducted sediments with mantle peridotite.Zircon U-Pb dating reveals that the high-Mg diorite crystallized at 313.6±2.4 Ma,i.e.,late Carboniferous.Combining our data with the temporal and spatial distribution of the Diyanmiao SSZ-type ophiolite,we propose that the eastern Paleo-Asian Ocean had not closed by the late Carboniferous,but intra-oceanic subduction was ongoing.A new model of the initiation of subduction in the eastern PAO during the late Paleozoic. 展开更多

The Xing'an-Inner Mongolia Orogen is a critical tectonic unit for constraining the evolution of the Paleo-Asian Ocean.However,the location and time of the closure of the Paleo-Asian Ocean are still debated.Here,we select a representative basin in Dashizhai in northeastern China,using U-Pb zircon geochronology and geochemistry to analyze the sedimentary facies,depositional ages,and provenance.The results show that the ages of the Dashizhai Formation range from 400 to 347 Ma,the Shoushangou Formation range from 400 to 348 Ma,the Zhesi Formation range from 307 to 252 Ma,and the Linxi Formation range from 299 to 241 Ma.The Dashizhai Formation is composed of metamorphic andesite and clastic rocks.The Shoushangou Formation comprises siltstone,rhyolite,and argillaceous siltstone.The Zhesi and Linxi Formations are composed of mudstone and argillaceous siltstone.Geochemical data shows that these rocks are enriched in light rare earth elements and depleted in Eu with various La/Sc,Th/Sc,and La/Co ratios.The Permian Dashizhai Basin is from Permian volcanic and felsic igneous rocks from the Ergun,Xing'an,and Songliao blocks.The absence of the Late Carboniferous strata in the Dashizhai Basin indicates an extension setting during this period.Furthermore,we suggest the Xing'an-Inner Mongolia Orogen was an uplifting process associated with evolution the Paleo-Asian Ocean during the Late Permian. 展开更多

The effects of land use changes on poverty vary markedly among geographic regions.While Inner Mongolia has been experiencing significant land use changes during past decades,to date there has been no systematic research aimed at understanding how these land use changes affect poverty in the region.This study analyzes spatiotemporal patterns of land use changes in Inner Mongolia from 1980 to 2020 through the application of statistical methods including Correlation Analysis,Multiple Stepwise Regression Analysis,and Geographically Weighted Regression to understand how land use changes affect the distribution and dynamics of poverty.We show that five types of land use conversion explain 51% of the variation in poverty levels.Conversions among cultivated land,grassland,and construction land are shown to have dominated the pattern of land use change in Inner Mongolia.From 2000 to 2020,2,208 km2of grassland and 56 km2of water/wetland were converted to builtup land,and 32 km2of water/wetland was converted to woodland,these conversions promoted poverty reduction.Conversely,the conversion of existing cultivated land to grassland and its degradation to unused land(1,754 km2and 156 km2,respectively)has constrained progress in alleviating poverty in the region.Accordingly,further mitigation of poverty in Inner Mongolia can be obtained through interventions that conserve remaining cultivated land,while simultaneously facilitating urbanization.Maintaining the dynamic balance between economic growth and environmental protection is key to the development of policies that advance sustainability in this region.Moreover,the methodology used in this study has the potential to be applied to other regions of the world with similar environmental and socioeconomic conditions to support sustainable land use planning in the context of poverty reduction. 展开更多

As a critical ecological barrier in northern China,Inner Mongolia provides key ecosystem services(e.g.,forage supply,soil retention,carbon sequestration)but faces ongoing risks such as land desertification,water scarcity,and biodiversity loss.This study analyzes spatiotemporal variations in ecological risk(ER)and ecosystem service value(ESV)from 2000 to 2020,revealing complex dynamics shaped by both natural processes and human interventions.The results demonstrate dramatic ESV fluctuations,with grassland values showing a V-shaped trajectory(−11.1%during 2000–2010 followed by+11.7%recovery),wetland values declining 5.8%then recovering 4.1%,and forest values initially increasing 9.1%before decreasing 7.5%,resulting in an overall ESV decrease of 2.0%followed by a 1.9%rebound.Ecological risk patterns remained relatively stable,with mid-low risk dominating(56.45%in 2000 to 56.19%in 2020)and high-risk zones consistently below 0.5%coverage,though wetlands accounted for over 97%of these persistent high-risk areas.Analysis of service interactions revealed strong synergies between grain production and climate regulation(r=0.96),trade-offs between provisioning and other regulating services(r=−0.10 to−0.06),and increasing synergies among all risks by 2020(r=0.28–1.00).These patterns emerged from competing drivers including rapid urbanization(39.6%expansion of construction land),effective conservation policies driving grassland recovery,and climate variability.The findings highlight both the success of restoration measures in recovering grassland and wetland services and the ongoing challenges represented by persistent high-risk wetlands and declining forest values,underscoring the need for integrated strategies that combine targeted wetland protection,improved forest management,optimized grassland utilization,and careful balancing of cross-service trade-offs to ensure the sustainable development of this fragile yet vital ecosystem. 展开更多

The southern part of East Siberia(SES)is highly vulnerable to flooding caused by the extreme precipitation events(EPEs)during summer.Building on previously detected EPEs in SES and Mongolia,we examined wave propagation patterns for two periods:1982-98 and 1999-2019.Our analysis revealed distinct wave train configurations and geopotential anomalies preceding EPEs,with an increase in wave activity flux across the Northern Hemisphere,followed by a subsequent decrease during EPEs.Consequently,Eastern Siberia has experienced a significant rise in wave activity.Based on geopotential anomalies over Central Siberia accompanying EPEs,we identified two main types.The first,the ridge type,is predominant during the first period and features a meridional contrast with a positive geopotential(and temperature)anomaly over Central Siberia and a negative anomaly over the subtropical regions along the same longitude.The second type,termed the trough type,is more typical for the second period.It involves either a negative geopotential anomaly or the zonal proximity of positive and negative geopotential anomalies over Central Siberia.The trough type,marked by zonally oriented anomalies in geopotential and temperature,results in a more pronounced temperature decrease before EPEs and significant zonal temperature contrasts.Further,it is related to more stationary waves over Northern Eurasia,with persistent positive geopotential anomalies over Europe linked to quasi-stationary troughs over Central Siberia and positive anomalies east of Lake Baikal.Our findings align with shifts in boreal summer teleconnection patterns,reflecting significant changes in wave propagation patterns that have occurred since the late 1990s. 展开更多

Early childhood education(ECE)plays a fundamental role in shaping young children’s cognitive,social,and emotional development.This study explores the theoretical foundations of ECE by analyzing classical and modern philosophical perspectives and their impact on early childhood curriculum development,particularly in Mongolia.The research examines the key intellectual contributions of thinkers such as Plato,Rousseau,Pestalozzi,and Comenius,comparing them with contemporary theories from Piaget,Vygotsky,Erikson,and Bruner.Through this comparative analysis,the study identifies enduring principles that continue to influence modern ECE programs,including child-centered learning,holistic development,and the roles of educators and caregivers.Furthermore,the study evaluates how these foundational philosophies shape Mongolia’s childhood education curriculum,aligning traditional educational values with global pedagogical trends.The findings highlight the significance of integrating classical and modern theories to create a comprehensive and culturally relevant ECE framework.By synthesizing historical insights with contemporary practices,this study contributes to the ongoing discourse on optimizing early childhood education policies and curricula for children’s holistic development in a rapidly evolving educational landscape. 展开更多

People that herd livestock for a living are known as herders,and they are found throughout Mongolia’s wild vast steppe.The purpose of the study is to investigate herder parents’belief systems for preparing the un-preschooled children for schooling in the context of herder community in rural Mongolia.The belief systems of herder parents are shaped by three main characteristics:They lack a clear plan for their children’s education,are deeply concerned about it,and feel incapable of preparing their children for formal schooling.Herders’lives revolve around their livestock,and they must remain flexible,moving when necessary due to factors like water scarcity and poor grazing conditions caused by insufficient rain.While they desire better education for their children,the nomadic lifestyle makes it difficult to achieve.Herder parents’attitudes are contradictory;they want their children to be educated and live in urban areas,yet they also prefer them to become herders rather than educated but unemployed individuals.The hard work of herding makes them reluctant to pass it on to the next generation. 展开更多

The vegetation coverage dynamics and its relationship with climate factors on different spatial and temporal scales in Inner Mongolia during 2001-2010 were analyzed based on MODIS-NDVI data and climate data. The results indicated that vegetation coverage in Inner Mongolia showed obvious longitudinal zonality, increasing from west to east across the region with a change rate of 0.2/10N. During 2001-2010, the mean vegetation coverage was 0.57, 0.4 and 0.16 in forest, grassland and desert biome, respectively, exhibiting evident spatial heterogeneities. Totally, vegetation coverage had a slight increasing trend during the study period. Across Inner Mongolia, the area of which the vegetation coverage showed extremely significant and significant increase accounted for 11.25% and 29.13% of the area of whole region, respectively, while the area of which the vegetation coverage showed extremely significant and significant decrease accounted for 7.65% and 26.61%, respectively. On interannual time scale, precipitation was the dominant driving force of vegetation coverage for the whole region. On inter-monthly scale, the change of vegetation coverage was consistent with both the change of temperature and precipitation, implying that the vegetation growth within a year is more sensitive to the combined effects of water and heat rather than either single climate factor. The vegetation coverage in forest biome was mainly driven by temperature on both inter-annual and inter-monthly scales, while that in desert biome was mainly influenced by precipitation on both the two temporal scales. In grassland biome, the yearly vegetation coverage had a better correlation with precipitation, while the monthly vegetation coverage was influenced by both temperature and precipitation. In grassland bi- ome, the impacts of precipitation on monthly vegetation coverage showed time-delay effects. 展开更多

Different government departments and researchers have paid considerable atten- tion at various levels to improving the eco-environment in ecologically fragile areas. Over the past decade, large numbers of people have emigrated from rural areas as a result of the rapid urbanization in Chinese society. The question then remains： to what extent does this migra- tion affect the regional vegetation greenness in the areas that people have moved from？ Based on normalized difference vegetation index （NDVI） data with a resolution of 1 km, as well as meteorological data and socio-economic data from 2000 to 2010 in Inner Mongolia, the spatio-temporal variation of vegetation greenness in the study area was analyzed via trend analysis and significance test methods. The contributions of human activities and natural factors to the variation of vegetation conditions during this period were also quantita- tively tested and verified, using a multi-regression analysis method. We found that： （1）the vegetation greenness of the study area increased by 10.1% during 2000-2010. More than 28% of the vegetation greenness increased significantly, and only about 2% decreased evi- dently during the study period. （2） The area with significant degradation showed a banded distribution at the northern edge of the agro-pastoral ecotone in central Inner Mongolia. This indicates that the eco-environment is still fragile in this area, which should be paid close at- tention. The area where vegetation greenness significantly improved showed a concentrated distribution in the southeast and west of Inner Mongolia. （3） The effect of agricultural labor on vegetation greenness exceeded those due to natural factors （i.e. precipitation and tempera- ture）. The emigration of agricultural labor improved the regional vegetation greenness sig- nificantly. 展开更多

Mongolia is an important country in the Economic Corridor of China-Mongolia-Russia, a deep understanding of the coupling relationship between urbanization and the eco-environment in Mongolia is meaningful to achieve green development of the Belt and Road. The entropy method and coupling coordination degree model were integrated to evaluate the coupling coordination degree between urbanization and the eco-environment in Mongolia during 2000-2016. The results showed that the coupling coordination degree between urbanization and the eco-environment in Mongolia was generally at the stage of seriously unbalanced development, and that the main contributor of the urbanization and the eco-environment subsystem were demographic urbanization and eco-environment endowment, respectively. The southern part of Mongolia central zone should be paid more attention due to the lower degree of coupling coordination between urbanization and the eco-environment. To promote the healthy urbanization development in Mongolia, six-layer eco-city establishing green development pattern is proposed to provide scientific support for Mongolia. 展开更多
