摘要

Based on DEM data and conventional data of precipitation at 114 meteorological stations in Shandong Province during 1971-2010,the statistical model of annual average precipitation in Shandong Province was established using SPSS software; DEM data and raster data of latitude and longitude were substituted into the statistical model,and the spatial distribution of annual average precipitation in Shandong Province based on the statistical model was obtained with the aid of Arc GIS software. Afterwards,the difference between actual value of precipitation at stations used in interpolation and simulated value was interpolated using Kriging interpolation method to obtain residual error of precipitation. Finally,the raster data of annual average precipitation based on the regression model were overlaid with residual error of precipitation to obtain the spatial distribution map of annual average precipitation in Shandong Province. It is verified that the simulation result has high accuracy and can reflect the spatial distribution of precipitation in Shandong Province.
