Abstract
Tuwei River Basin is a sensitive region of soil erosion, which located in midstream of Yellow River. The vegetation coverage is one of the most important factors to affect the amount of soil erosion. In order to analyze the dynamic change of vegetation coverage in Tuwei River Basin from 2000 to 2013, MODIS Enhanced Vegetation Index ( EVI) data were used to extract the series characteristics of vegetation changes. The method for reconstructing EVI time- series data set based on the Time series reconstruction Savitzky- Golay filter was application for noise reduction. Finally, we analyzed the spatial and temporal variations of the vegetation coverage in the Tuwei River Basin. The results showed that from 2000 to 2013 the total vegetation coverage had a trend of improvement and ecological conditions were getting for the better.
