Abstract Soil erosion is one of important factors which results in environment deterioration. Soil loss equation can be used to evaluate the dynamic development of the soil resource and develop plans for controlling soil erosion. The equation can be applied to assess the benefits of soil loss control practice. Experimental data of about 1000 annual rainfall plots in Beijing were used to develop Beijing soil loss equation. The algorithm or data of every factor in the equation has been determined. The development of the equation can be used as a tool for soil loss dynamic monitoring in Beijing and for soil and water conservation planning.
