Wind power has been developing rapidly as a key measure to mitigate human-driven global warming. The under-standing of the development and impacts of wind farms on local climate and vegetation is of great importance for their rational use but is still limited. In this study,we combined remote sensing and on-site investigations to identify wind farm locations in Inner Mongolia and performed landscape pattern analyses using Fragstats. We explored the impacts of wind farms on land surface temperature (LST) and vegetation net primary productivity (NPP) between 1990 and 2020 by contrasting these metrics in wind farms with those in non-wind farm areas. The results showed that the area of wind farms increased rapidly from 1.2 km2 in 1990 to 10,755 km2 in 2020. Spatially,wind farms are mainly clustered in three aggregation areas in the center. Further,wind farms increased nighttime LST,with a mean value of 0.23 ℃,but had minor impacts on the daytime LST. Moreover,wind farms caused a decline in NPP,especially over forest areas,with an average reduction of 12.37 GC/m2. Given the impact of wind farms on LST and NPP,we suggest that the development of wind farms should fully consider their direct and potential impacts. This study provides scientific guidance on the spatial pattern of future wind farms.
