Abstract: Soil erosion models are important technique instruments of knowing soil erosio n processes and intensity, mastering soil resource developing trends, directing people to use soil resource reasonably, and managing and maintaining human long time live environment; therefore they are paid attention to by the world countriesThis paper summarizes main achievements of the soil erosion models in China, introducing e xperience statistic models, physical cause models and foreign models applied in China in detail On the base of summarizing and evaluating Chinese soil erosion models, this paper brings forward future developing directions that t he soil erosion models should pay attention to:(1)paying attention to the theor y researches of soil erosion models, consummating from erosion factors basis erosion predict ion to erosion processes quantity and theory researches, studying each erosion f actor and its interaction impact on erosion processes, and sediment dispersion, transportation and deposition action on complex slopeland, as well as different catchments scales; (2) reinforcing the study of gravitation erosion and cave ero sion mechanism, and big and middle scale catchments erosion models.

Key words: devel oping directions, main achievements, soil erosion models
