With the help of GIS software, the impact factors for spatial distribution of precipitation and the influence brought by rainstorm were analyzed. The results showed that terrain factors were effective for the estimation model of rainstorm in Jiangxi, especially large reservoir. Moreover, spatial distribution characteristics of the actual precipitation under the multiple linear regression model were estimated.展开更多
