In the acquisition of comprehensive graphics information and on the basis of written information,Universal Soil-loss Equation(USLE model) which is used in common in the USA and the Relative Wind Erosion of Soil Model are established for the soil water erosion and wind erosion of Taipusi County.

By correlation analysis on the runoff and soil loss for 364 times rainfall,a simple and convenient mathematical formula that is suitable to calculate rainfall erosion factor R value for local area was established and other factors of USLE model were also determined.

By correlation analysis of runoff and soil loss from 364 events of rainfall,a simplified and convenient mathematical formula that is suitable to calculate rainfall erosion factor R value for the local region was established and other factors of USLE model were also determined.
