Abstract

Annual mean NDVI of different Vegetation types during growing season are extracted from MODIS 8-day composite 500m reflectivity data in Inner Mongolia from 2000 to 2011 to analyze vegetation dynamic change and its spatial variation trends. It is shown that annual mean NDVI of different vegetation types has a slight upward trend during the past 12 years and the overall vegetation cover increases slightly. Area of improved vegetation is larger than degradated area and one third area basically no vegetation change, spatial pattern of vegetation cover change shows evident differences between regions.
