Abstract A time series of SPOT-VEGETATION Normalized Difference Vegetation Index (NDVI) data with 1 km×1 km spatial resolution were used to monitor the vegetation cover change during the period of 1998 to 2004 in Northwest China. The MVC (Maximum Value Composites) method and the linear regression were used to characterize the trends in vegetation cover change. And the landuse map of Northwest China was used to analysis the NDVI variety of different landuse types. During the last 7 years, the vegetation degradation was popular in most regions of Northwest China. However, there were some regions where vegetation cover was increasing, but the increasing range was smaller than the decreasing range on the whole. The results indicated that the improved regions of vegetation cover mainly appeared in the major part of Shaanxi and Ningxia province and in the northwest and southeast parts of Xinjiang. But in the most part of Northwest China, the NDVI was reducing. However in the same particular year, the patterns of NDVI variety of different vegetations were in the similar tendency.
