Runoff causes soil erosion and environmental pollution. It is very important for soil loss calculation and soil and water resources evaluation to select suitable runoff calculation method. The 30 single storm data of two conventional tillage plots at Puwa watershed, Fangshan County and 13 single storm data of one fallow plot at Shixia watershed, Miyun County were used. Several runoff calculation methods, including GAML revised by Chu, Phillip, Horton, SCS curve number, were compared. The results showed that the model efficiencies of GAML and Phillip were higher than those of Horton and SCS curve number. According to the parameters easily obtained, GAML revised by Chu is suggested when there are the continuous records of rainfall in Beijing mountainous area. If not, SCS curve number should be used. The results can be served as soil and water evaluation and plan.
