摘要

Vegetation is sensitive to reflect the change of ecological environment, so it is significant to study the vegetation dynamics for ecological environment protection and ecological early warning. Based on the time series of the SPOT/VEGETATION NDVI dataset, this paper has obtained the spatial distribution of NDVI in Inner Mongolia (IM), analyzed the characteristics of NDVI change trend in the period of 1998-2008 by Maximum Value Composites (MVC) and Mann-Kendall test. The main findings are as follows: (1) NDVI time series in most regions of IM has tendency in the recent 10 years. (2) The significant increased areas of vegetation cover are mostly distributed in the area of severe desertification, and the significant decreased areas of vegetation cover are mainly located in the typical steppes.
