Abstract
The driving mechanism of vegetation change caused by climate change and human activities is of great scientific significance for ecological environment protection and sustainable development.This paper focuses on the spatio-temporal variation of NDVI and its response to climate change dur-ing 2002-2021.The results showed that:(1)Inter-annual NDVI in central and western Inner Mon-golia showed a fluctuating upward trend,and the spatial distribution was higher in central Inner Mon-golia and lower in western Inner Mongolia.(2)Based on trend analysis and Hurst index to explore the future change trend of NDVI,it can be seen that the areas with continuous increase,from increase to decrease,transition from increase to decrease,transition from decrease to increase,and continuous decrease account for 73.4％,16.0％,1.2％,and 9.2％respectively.(3)The average partial correla-tion coefficient between NDVI and average temperature in the study area is 0.09,and the average par-tial correlation coefficient between NDVI and precipitation is 0.37.(4)Climate change promoted vege-tation growth in 86.72％of central and western Inner Mongolia;Human activities promoted vegeta-tion growth in 84.58％of central and western Inner Mongolia.关键词
