Abstract：The study was to estimate the rainfall erosivity of Beijing and analyze the spatial distribution. Precipitation data from 20 weather stations in Beijing were used. The results indicated the equation R= 5.256 2FF1.305 7 was fit for estimating the erosivity, in which FF was an index based on monthly rainfall amount. With the equation, for each of 113sites of Beijing, the erosivity was calculated and an isoline map of erosivity was plotted. It is found from the map that the Rainfall erosivity of Beijing varied from 2 214.0 to 6 682.7 MJ·mm·hm-22h·-1·a-1. The value of erosivity was high in the northern and western mountainous area, then decreased to eastern and southern direction.
