Paper Abstract

The paper gives a quantitative analysis on soil erosion in Shanchonghe watershed. The quantitative analysis is based on a revised universal soil loss equation (RUSLE), supported by geographic information system (GIS) and remote sensing (RS) technology, and according to the landform, rainfall, vegetation data, etc., in Shanchonghe watershed, which are obtained from interpreted data of Shanchonghe watershed RS image and it’s statistics data. The results showed that the annual soil erosion modulus in Shanchonghe watershed is 19.05 t / (hm2*a), the annual soil erosion amount is 2744.23 t/a. The soil erosion spatial distribution is very different. These areas have strong soil erosion, which height is more than 2000 meters above sea level, or which slope is bigger than 25 degree, or bare surfaces, or sloping farmlands. These are the focus areas of governance of soil erosion in Shanchonghe watershed. The study provides scientific basis to water and soil conservation work in Shanchonghe watershed.
