摘要：
We used the normalized difference vegetation index (NDVI) data of the MODIS images in the Wei River Basin of the Loess Plateau from 2000 to 2016 based on the support of RS/GIS technology. The results indicate that: (1) The vegetation cover in the Wei River Basin has accelerated and improved since 2000. Afterwards, the vegetation decreased slightly; (2) More than 90% of the area in the past 17 years showed vegetation restoration. The significant recovery area mainly accounted for 6.80% of the vegetation reduction area in the Ziwuling and Liupanshan areas, and was mainly attributed to the urbanization process. The acceleration of the results further confirms the remarkable achievements of the ecological restoration project on the Loess Plateau and provides theoretical support for regional sustainable development.
