Description :
A mapping method was developed by integrating remote sensing parameters to identify eroded areas under high density canopy in the Changting County, Fujian Province. The remotely sensed vegetation indices, vegetation fractional canopy (VFC) and leaf area index (LAI) were calibrated based on soil erosion measurements from previous runoff plot experiments and extrapolated from USLE modeling to a regional scale. It is highlighted that the vegetation restoration degree determined from LAI is more sensitive to subcanopy soil erosion than from VFC. Therefore, the remote sensing based method can be used for operational erosion monitoring in southern China.
