- Abstract:
-
Monitoring and assessing vegetative land cover change is important to resources management and environmental change study. This paper, using the 1 km SPOT Normalized Difference Vegetation Index (SPOT/NDVI) (1998-2006) data in growing seasons (April-September), assessed the vegetative land cover change in Wujiang River Basin (WRB), Southwest China from 1998 to 2006. The final results demonstrate that vegetative land cover show slight trend of amelioration in general during the past years, while in some areas (Guiyang, Zunyi) vegetative land cover degrade or decrease because of over grazing/farming or urbanization. Cropland and grassland are also found easily degraded than forest and shrubs in this area. All these finding may serve as a strong basis for decision making in regard to land resource management and environmental rehabilitation.
