Abstract
Based on the amended model of RUSLE universal soil loss equation and GIS technology, combined with the natural geographical features of Great Khingan, it has conducted quantitative analysis of the factor in Soil loss equation. Uses 2000 and 2010 years TM images classification are land uses/cover type figure, we gets all factors values of space distribution in the RUSLE model, gets soil erosion volume estimates data and soil erosion strength distribution figure based on grid cell data and obtained Great Khingan soil erosion strength grade distribution figure and through the terrain niche index and spatial center of gravity transfer model theory, revealed soil erosion in the temporal and spatial evolution of Greater Khingan in 11 years. Study results indicate that during the 2000 and 2010 period, the amount of soil erosion in Greater Khingan shown overall upward trend, the slightly erosion area is reduced, the low erosion area is increased, several other types of erosion intensity had no obvious change.
