Zha Liang-song

Abstract

Base on 30 years precipitation data of 78 Weather Sites in Anhui province,using the spatial interpolation technique served by GIS,the paper studied the spatial distribution of precipitation in Anhui.through tested the result of spatial interpolation about 17 test points,obvious relevance,this show that the method of spatial interpolation of precipitation based on IDW interpolation model was more efficient.
