Abstract: The core of water and soil loss evaluation, which has developed and evolved since 1950s, lies in the quantitative models with the formula and algorithm of parameters. This paper reviews the development and evolution of GIS-based remote sensing evaluation models, as well as algorithm for values of each factor and its empirical value, compares USLE and CSLE with their factor algorithms, and finally proposes the equation applicable to China.
