Five factors expressing greenbelt quality and one factor expressing quantity were adopted for evaluation of the residential greenbelt, and the AHP （Analytical Hierarchy Process） method was used to determine the value of factors. Thirty residential areas were selected as the samples. Two principal components were extracted and their expression was constructed by method of factor anlysis, therefore, quality evaluation of residential greenbelt was obtained. The accuracy of the function and implement quality classification toward the residential greenbelts in Xinxiang City were validated by clustering analysis method. The results showed that the greenbelt quality of fourteen residential areas was higher than the average level, of which eleven were newly-built residential areas. The 30 residential areas were classified into three types according to their greenbelt features and their formation by clustering analysis method. Finally rational proposal basing on aforesaid evaluating results was proposed for construction and renewal of residential greenbelt, upon which directive basis was provided for construction and renewal of residential greenbelt. 展开更多

[Objective] The aim was to study on effects of greenbelts in different varieties on temperature drop under solar thermal radiation. [Method] In residential regions, effects of temperature reduction by five varieties of greenbelts （megaphanerophyte, dungarunga, shrub, herbaceous plant and bare land） and changing rules with days under the same solar thermal radiation were researched. [Result] Greenbelts＇ temperature changed with intensity of solar thermal radiation, among which greenbelt of megaphanerophyte absorbed, transfered and reflected thermal radiation through crown canopy. Temperature of underlying surface was reduced accordingly, where correlation between underlying surface＇s temperature and solar thermal radiation （R） was 0.156 and the temperature declined by 1.9 ℃. In contrast, correlation of temperature of underlying surface （of lawn） with solar thermal radiation （R） was as high as 0.820, but the temperature only declined by 0.6℃. [Conclusion] The established linear relationship between crown＇s temperature and air temperature actually provides references for temperature measurement of greenbelts at scale. 展开更多

Urban expansion of cities has caused changes in land use and land cover(LULC)in addition to transformations in the spatial characteristics of landscape structure.These alterations have generated heat islands and rise of land surface temperature(LST),which consequently have caused a variety of environmental issues and threated the sustainable development of urban areas.Greenbelts are employed as an urban planning containment policy to regulate urban expansion,safeguard natural open spaces,and serve adaptation and mitigation functions.And they are regarded as a powerful measure for enhancing urban environmental sustainability.Despite the fact that,the relation between landscape structure change and variation of LST has been examined thoroughly in many studies,but there is a limitation concerning this relation in semi-arid climate and in greenbelts as well,with the lacking of comprehensive research combing both aspects.Accordingly,this study investigated the spatiotemporal changes of landscape pattern of LULC and their relationship with variation of LST within an inner greenbelt in the semi-arid Erbil City of northern Iraq.The study utilized remote sensing data to retrieve LST,classified LULC,and calculated landscape metrics for analyzing spatial changes during the study period.The results indicated that both composition and configuration of LULC had an impact on the variation of LST in the study area.The Pearson's correlation showed the significant effect of Vegetation 1 type(VH),cultivated land(CU),and bare soil(BS)on LST,as increase of LST was related to the decrease of VH and the increases of CU and BS,while,neither Vegetation 2 type(VL)nor built-up(BU)had any effects.Additionally,the spatial distribution of LULC also exhibited significant effects on LST,as LST was strongly correlated with landscape indices for VH,CU,and BS.However,for BU,only aggregation index metric affected LST,while none of VL metrics had a relation.The study provides insights for landscape planners and policymakers to not only develop more green spaces in greenbelt but also optimize the spatial landscape patterns to reduce the influence of LST on the urban environment,and further promote sustainable development and enhance well-being in the cities with semi-arid climate. 展开更多

[Objectives]The paper was to investigate the garden greenbelt in 30 sample plots such as parks,roads,communities,etc.in Shijiazhuang City.[Methods]The species,abundance and frequency of weeds in the greenbelt of public gardens were recorded through point-line-surface investigation,and typical plants were sampled.[Results]There were 56 species of alien invasive plants in garden greenbelts of Shijiazhuang City,belonging to 44 genera and 20 families.In terms of life form,herbaceous plants were absolutely dominant,accounting for 92.8%of the total.The most alien invasive plants were native to America,accounting for 66.1%of the total.In terms of introduction path,the plants introduced artificially and unintentionally accounted for almost half.The species and quantity of alien invasive plants were related to the size of greenbelt area,the length of the build time of the surveyed plot,the composition structure of greenbelt and the level of green management and protection.There was larger distribution of alien invasive plants in the sample plots with large greenbelt area,long build time,herbaceous-dominated greenbelt and low level of green management and protection.Among the 56 alien invasive plants,3 plants were toxic.From the perspective of invasiveness,the alien invasive plants in the garden greenbelt of Shijiazhuang City could be divided into 5 levels:invasive alien species of malignant consequences,invasive alien species of severe consequences,invasive alien species of partial consequences,invasive alien species of average consequences,and invasive alien species to be observed.[Conclusions]This study will provide a reference for the prevention and control of alien plant invasion,and lay a foundation for the prevention and control of existing invasive plants. 展开更多

Four urban greenbelt types including roadside greenbelt, resident-area greenbelt, landscape forest, and forest park, were simultaneously investigated in Shenzhen, China, in such measures as air temperature, air humidity, wind speed, air anion ratio, and inhalabal particle concentration, which were strongly related with pleasing feeling of human body. The results show that the average air temperature in both forest park and landscape forest is much closer to the pleasing feeling of human body temperature than that of the rest two greenbelts, where it is 1.782 ℃ and 0.837℃ in forest park as well as 3.084 ℃ and 2.140 ℃ in landscape forest less than that of roadside and resident-area greenbelts, respectively. In terms of mean air humidity, forest park and landscape forest are 3.034% and 7.563% higher than that of roadside greenbelt, and 1.205% and 5.734% higher than that of resident-area greenbelt, respectively, implying a sound humidity feeling of human comfort in the former two types. The air cleanness holds a descending rank as forest park, landscape forest, resident-area greenbelt, and roadside greenbelt, whereas the rank in inhalable particle concentration is completely reverse. In general, landscape forest and forest park that mainly consist of trees have a comparatively higher feeling of human comfort whereas roadside and resident-area greenbelts fluctuate irregularly to some extent for the measures studied. The four greenbelt types investigated could be summarized in human comfort as the following descending rank, forest park, landscape forest, resident-area greenbelt, and roadside greenbelt. 展开更多

随着城市化的快速发展,大气污染尤其细颗粒物(PM2.5)已成为制约城市环境的重要因素,相关研究表明,在众多的PM2.5来源中道路交通是在其中的重要来源之一,而道路绿地植物群落能够消减来自道路的PM2.5。运用场地观测和ENVI-met模拟相结合... 随着城市化的快速发展,大气污染尤其细颗粒物(PM2.5)已成为制约城市环境的重要因素,相关研究表明,在众多的PM2.5来源中道路交通是在其中的重要来源之一,而道路绿地植物群落能够消减来自道路的PM2.5。运用场地观测和ENVI-met模拟相结合的方法探讨城市道路绿地植物群落对PM2.5的影响,分析仅有乔木(i)、乔木+树篱(ii)、乔木+树篱+灌木(iii)3种模式下的植物群落配置对PM2.5的影响,揭示绿地植物群落的长度、宽度、高度和LAI对PM2.5的影响。结果表明:(1)场地观测中的道路绿地植物群落的3种配置模式对PM2.5的消减率分别是iii(14.2%)>ii(12.9%)>i(9.2%)。(2)绿地中植物的种类、绿地宽度、绿地植物的叶面指数等要素对消减作用起正面作用,高度和长度起负面作用。(3)绿地的长度的一定量的减少可以在绿地后方形成一个宽度约为绿地长度80%的、随着与绿地的距离的增加而宽度递减的较绿地长度更长环境PM2.5浓度更低的低谷区,但其他没有绿地的空间的PM2.5浓度会加重。(4)绿地高度的增加会迫使PM2.5向更高的空间运动。 展开更多
