| Abstract: | The soil erosion of the Yellow River Basin in Gansu is very serious. The main type is water erosion. The frozen thaw erosion and wind erosion just distribute in part of regions. The main driving factors are natural factors and manmade factors. The natural factors include loose structure of the regional soil, centralized rainfall with higher slope, bad vegetation cover in the most of regions. The manmade factors include reclamating the waste land with high slope which meets the increasing population, over grazing, forest destroying and developing and constructing projects. |
