The erosion of longstanding research in general and a number of studies on Huong river basin is largely based on the universal soil loss model of Wischmeier and Schmid (USLE) to calculate the amount of land is separated from the rib, which not onlyl space of the distribution of material erosion and soil loss is real - the flow was sent. To address these limitations, the paper used N-SPECT model combined with GIS technology to assess risk of soil erosion in Huong river basin. Evaluation results show that volume erosion in Huong river basin can be up to over 1.5 t /(ha/year), concentrated in areas with slopes greater length and poor vegetation cover, as in the communal areas Phong My, Phong Son, Phong Xuan (Phong Dien district), the communal areas Hong Kim, Huong Nguyen, Phu Vinh, A Roang (A Luoi district), the communal areas Huong Huu. Huong Loc, Huong Phu, Thuong Lo, Thuong Nhat (Nam Dong district).
