Description :
This study used net primary productivity (NPP) as an important indicator of the arid and semi-arid ecosystem's productivity to estimate the impacts of the land use and land cover change (LULCC) driven by ecological restoration programs in Xinjiang from 2001 to 2009. The modeling method was based upon the Carnegie–Ames–Stanford Approach (CASA) terrestrial carbon model and Moderate-resolution Imaging Spectroradiometer (MODIS) remote sensing data and meteorological data for modeling simulation. The results demonstrated that the forest area of Xinjiang had the most net increase. The most dominant land cover changes during 2001–2009 were from grassland to forest and mutual transformation between grassland and desert. Compared to climate change, human activities produced an obvious positive effect in the increase of total NPP, especially for forest land. As a result, ecological restoration programs produced positive impacts on forest expansion and carbon sequestration in Xinjiang.
