Abstract

Taihang mountain area in Hebei province being taken as research area,in this paper the rainfall,slope,slope length,gully density,soil texture,vegetation fraction and land-using patterns were selected as seven influential factors,soil erosion evaluation index system was established with AHP method.With support of RS and GIS,the influential factors were graded and the weight of map algebra was used to devide the soil erosion intension grade and based on this,the distribution of soil erosion intension in 2000 was revealed.
