Study on Quantitative Monitoring Soil Loss in Small Watershed Base on GIS and RS

Yaolin Liu, Zhijun Luo

Abstract

A quantitative method of RS for monitoring soil losses based on GIS and the formula and algorithm of each model factor about the revised universal soil loss equation(RUSLE) are described in this paper,the spatial distribution law of soil erosion is discussed and the amount of soil loss of the small watershed is predicted running the model of RUSLE by the support of GIS.
