Abstract

Abstract:

In order to improve ecosystem functions and prevent vegetation degradation in the Heihe River Basin， China has implemented a series of ecological protection projects in the Heihe River Basin since 2000. It is of great significance to quantitatively isolate the contribution of ecological projects from the effect of climate change to better assess the effectiveness of these projects. Based on NDVI and climatic datasets in the Heihe River Basin， this study adopted trend analysis to derive the spatial and temporal patterns of vegetation dynamics， and used the combined partial correlation analysis and residual analysis to distinguish the impact of climate change from that of ecological protection projects on vegetation from 1982 to 2017. The results showed that：（1） NDVI exhibited an upward trend in the Heihe River Basin from 1982 to 2017， especially after 2000. （2） Temperature and precipitation had a positive effect on the NDVI， and the increase in precipitation made more contribution to the greening trend. （3） After the implementation of the ecological protection project in 2000， the impact of human activities dominated the change of NDVI. The implementation of ecological construction projects explained up to 30.18% of the total variance of NDVI， and the contribution was even more in cultivated lands and forests. We concluded that the ecological protection projects played an important role in the greening of vegetation in the Heihe River Basin. Our research could improve the understanding of vegetation dynamics in the Heihe River Basin and provide scientific evidence for promoting ecological construction and sustainable development in arid areas.
