New Trend in Soil Erosion Research

Soil erosion models are important technique instruments of knowing soil erosion processes and intensity,predicting of soil and water loss and guiding the reasonable configuration of land resource.In this paper,the soil erosion models at home and abroad were evaluated,and the future developing directions of the soil erosion models were summarized: pay attention to the theory researches of soil erosion models,transform the erosion prediction based on erosion factors to the erosion processes quantification and theory perfecting,making the best use of advanced RS,GIS technology and BP neural network to provide plentiful data for erosion models researches to facilitate the test of soil erosion models,accelerate the estimation on the eco-economic loss by soil erosion,and focused on this actual situation of soil nutrient loss resulted from soil erosion,according to the differences in the soil nutrient loss,propose guidance in order to improve and protect the soil,and the reasonable farming.
