The quantitative evaluation of soil erosion in China began in 1950s.Some empirical models for soil erosion evaluation were developed in the early 1980s And physically-based models has been developed since the late 1980s.Meanwhile

the larger regional and even national evaluations of soil erosion and conservation were made.The quantitative assessment on soil loss and conservation in China can be divided into three scales

i.e.hillslope-small catchment-region or whole nation

and two types

i.e.empirical and physically-based models.Further researches should be focused on introducting overseas models

making models to be unification and generalization

intensifying the applications of remote sensing and GIS

and developing a complete erosion model system of China.
