Study on estimation of the amount of soil erosionin small watershed based on GIS and RS

Zhijun Luo

Abstract

Abstrcat This paper introduces the model of Revised Universal Soil Loss equation (RUSLE) and the algorithm of its each factor. And it builds the environmental database through a lot of data obtained from Remote Sensing(RS) and field surveys in the Taipingxi small watershed of the Three-Gorge area. Finally, the amount of soil erosion of the small watershed is estimated running the model of RUSLE by the support of Geographical Information System(GIS).
