Soil and Water Conservation Factors of Longmengkou Monitoring Sites in Yangpai River Watersheds

Longmenkou soil and water conservation monitoring site located on the Yangpai River watershed in Yaoan County,which are typical ecological restoration region.Using the observation data in recent 5 years, we analyzed the soil erosion factor of run-off plots located in disturbed grassland,forest of soil and water conservation,natural recovery land and terraced land which is built from slop land to further study the change law of soil erosion factor in different vegetation management measures.This paper provided a theoretical reference to the control of soil erosion in small watershed future planning about measurements of soil and water conservation.
