Abstract:: In order to estimate rainfall erosivity accurately and analyze the spatial distribution and temporal change of rainfall erosivity, a monthly rainfall erosivity model was adopted to calculate the rainfall erosivity in Zhejiang province by using daily rainfall data from 508 stations during 1956-2005. The results show that the spatial distribution of the R value appears increasing trend from north to south. The seasonal distribution of the R value is centralized and the percentage of R value from April to September is 77.7%. According to the seasonal changing character of R value, three regions are classified in Zhejiang province; The C_V of R value of year is higher in southeast coastal and island than other region in the spatial distribution.
