| Abstract: | Soil erosion can result in land degradation and sediment deposition of a river, where soil erosion is connected with some natural factors and human activities. Using ArcView 3.2 and Arc/Info 8.1 as the work platform, relations between soil erosion and terrain slope, between soil erosion and land use/land cover, between soil erosion and soil types of Lancang river basin in Yunnan Province are analyzed according to the results of map layers intersection and statistics analyzing. Finally, soil erosion of 1 km wide buffers of river and road in the same area is also studied. |
