- Abstract:
- Runoff and sediment production on different types of slope land are researched according to runoff plots observation in western plateau of Yunnan Province.Results show that shrub and natural secondary forest are good at protecting soil from erosion.The two types of land can decrease runoff amounts separately by 64.0% and 63.7%, and soil loss amounts by 82.1% and 74.5% than slope farmland.Slope grass land can decrease runoff and soil loss amounts respectively by 19.9% and (46.6%).All of runoff and soil loss have power function relationship with rainfall amounts and maximum rainfall intensity of 10 min.And soil loss increase with the runoff amounts increase directly.
