This paper mainly analyzed the soil erosion status before and after the Returning Farmland to Forest Project (RFFP) to evaluate the effects of RFFP on soil erosion with the help of USLE and GIS.The results showed that the mild erosion area decreased from 1 600.12km2 to 1 296.41km2 after the RFFP and mainly distributed in the Ning’an District; the extreme erosion area decreased from 3 161.52km2 and to 672.38km2,which was mainly replaced by the extreme erosion and conceptually distributed in the high altitude regions of Muling north and Linkou south,and <25° slope region of hilly areas.In a word,although the RFFP relieved the serious soil erosion status,but relative water and soil conservation measures should be still taken to thoroughly improve the worse soil erosion status,including terracing,contour farming and deep tillage and so on.But the fundamental measure was to develop the regional economy and adjust the agricultural production structure.Thus it could protect the achievements of the RFFP and ensure the sustainable development.
