Analysis of Vegetation Coverage Changes in Inner Mongolia with MODIS NDVI Images

摘要

This paper presented the distribution of vegetation fraction and analyzed its spatial-temporal variation between 2000 and 2010 in Inner Mongolia Autonomous Region. The Moderate-resolution Imaging Spectrometer (MODIS) normalized difference vegetation index (NDVI) data in the growing season in 2000 and 2010 were used for analyzing. We also explored the relationship between vegetation change and the precipitation factor. It indicated that the vegetation fractions in the study area became higher from west to east. Generally, the vegetation in 2010 grew better than that in 2000. The increasing regions of vegetation fraction were mainly distributed in northeastern region of Da Hinggan Ling and plains and hills in central and southern of Inner Mongolia. The decreasing regions were mostly distributed in Hulun Beuir plateau, southwestern region of Da Hinggan Ling and hills in the northern-central Inner Mongolia.
