- Abstract:
-
USLE/RUSLE is the central tool for soil erosion monitoring and forecasting. The accurate calculation of each factor value in the equation determines the accuracy of the equation application. Given that China's topographical conditions is of great difficulty, the application of equations in China has been limited. To analyze the key factors that shall be grasped in the calculation of each factor of the soil loss equation, as well as the main problems existing in the current research, we adopted the method of comprehensive comparison of literature and collected 373 related literatures through CNKI China Academic Journal Full-text Database and Web of Science. The comprehensive analysis results of the literatures show that the researches for each factor generally lack the selection of estimation formulas and the accuracy test of the estimation results, the formulas for slope length and slope factors have been misused, and the measures for crop coverage and management factors and soil and water conservation lack systematic quantitative calculations. The background conditions for calculating soil erodibility factors are very different, and it is difficult to make a horizontal comparison. To this end, two pieces of suggestions are put forward to improve the accuracy of the model. One is to establish a standardized ground monitoring system to systematically observe and establish a quantitative method for soil erosion factors. The other is to clarify the application boundary of this type of model and apply it in a more suitable environment.
