摘要

Using the rainfall data at Jiangxi Meteorological Observatory and 1∶50 000 DEM data of Jiangxi,spatial distribution characteristics of the rainstorm process on May 12,2012 were studied. 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.
