Abstract

Longdong region is known as one of the most serious soil erosion areas in the Loess Plateau of China. In this paper, Modified Soil Adjustment Vegetation Index (MSAVI) calculated from the shared Terra/MODIS data. Slope is derived from GTOPO-DEM data provided by the US Geological Survey (USGS). Soil Erosion Intensity of Longdong loess plateau region is calculated with the following three factors MSAVI, slope and average annual rainfall. Compared with previous soil erosion result produced in 1991, the two results match quite well, which shows that the remote sensing data of MODIS is applicable in rapid assessment of regional soil erosion.
