Study on the Soil Erosion Dynamic Changes in Songhuajiang River Watershed Based on RS and GIS

Abstract:

Based on the RS and GIS, the main data resource of Landsat TM image (1995 and 2005a) was used to study the soil erosion’s spatial-temporal dynamic changes. The results shown that: the reduced area of micro-level and slight soil erosion was 190.8 and 640 km2; the increased area of moderate and intensity soil erosion was 168 and 663 km2, the preserving ratio of micro-level erosion was greatest, intensity soil erosion’s persevering ratio was smallest, the transfer-out probability from intensity to micro-level soil erosion was greatest, the study results could give us some advice on making rational use of land and improving land use pattern the optimal allocation during developing the local economy.
