新疆风电场对生态环境的影响特征及其驱动因素分析OA

Against the backdrop of the"dual carbon"strategy,wind power,a leading clean renewable energy,is rapidly expanding into arid regions with abundant resources but fragile ecosystems.Xinjiang,one of China's most wind-resource-rich regions,urgently requires a quantitative assessment of the potential ecological effects of large-scale wind power development.Taking wind farms in Xinjiang as the study object,this work integrates mod-erate resolution imaging spectroradiometer data from 2000 to 2023 with meteorological,topographic,and land use data.Using the remote sensing ecological index(RSEI)and the geodetector model,we systematically investi-gate the spatial distribution of wind farms,temporal trends in ecological environmental changes,and their driving factors.The results indicate that(1)Wind farms in Xinjiang exhibit a clustered spatial distribution,mainly con-centrated in low-to-medium altitude regions such as Hami City,Turpan City,and Altay Prefecture.Site selection is primarily constrained by terrain flatness,land use types,and wind energy resources.(2)From 2000 to 2023,ap-proximately 81.8%of wind farm areas show a declining trend in RSEI.This suggests that although overall ecolog-ical quality remains relatively stable,localized degradation is evident.(3)Geodetector analysis reveals that mean annual precipitation(q=0.4522)and elevation(q=0.3949)are the dominant factors influencing ecological changes in wind farm areas.Interactions among factors such as mean annual temperature,slope,and wind farm operation-al duration are significant,with 89.3%of factor combinations exhibiting nonlinear enhancement effects,highlight-ing the multi-factor coupling characteristics of ecological effects.This study helps fill research gaps regarding the ecological effects of wind farms in Xinjiang.It provides a scientific basis for the coordinated management of wind power development and ecological protection,as well as for ecological assessments of renewable energy in arid regions.
