Paper Abstract

A time series of SPOT-VEGETATION Normalized Difference Vegetation Index (NDVI) data with 1×1 km2 spatial resolution are used to detect the vegetation cover change in west Songnen plain, Northeast China during the period of 1998 to 2006. The MVC (Maximum Value Composites) method and difference value method were used to analyze the inter-annual changes. Principal component analysis (PCA) of the time-series NDVI imageries was performed effectively for discriminating land covers. During the last 9 years, the vegetation degradation is popular in most regions of the study area. Though there are some regions where vegetation cover is increasing, the increasing amplitude is smaller than the decreasing amplitude on the whole.
