The Study on the Vegetation Factor C of the USLE Model in the Frigid Plateau Region Based on Remote Sensing

Article Preview

Abstract:

The vegetation factor C presented the human disturbance to the soil erosion and was important to the soil erosion estimation and soil conservation. However it was hard to be measured without a long term field observation and much harder in the frigid plateau region where the environment is fragile and tough, research needed and not easy to be conducted. This study used remote sensing to check detail land use/cover, estimated the factor C by vegetation rational model, and a factor C value table was built and C value map was drawn in the typical watershed of eastern Tibet to help to estimate the soil erosion in the material lack area.
