Elaborate Spatial Distribution Of Precipitation Of ChongQing On Terrain

Based on the 34 stations monthly precipitation and 100m 100m DEM of ChongQing,the paper study Spatial Distribution of Precipitation of ChongQing Based on GIS.accounting to the theory of mountanious climatology,The paper analyse the factors affecting Spatial Distribution of Precipitation, establish the model of Spatial Distribution of Precipitation. Calculate the Spatial Distribution of Precipitation.Depending on the relation of Precipitation and height above sea level, in view of the factors of height above sea level and terrain , the paper establish the model of Spatial Distribution of Precipitation on fluctuate terrain.The terrain affect Spatial Distribution of Precipitation by way of macroeconomics topographer and parcel height above sea level.the results show that The relativity of Precipitation and macroeconomics topographer is good in time scale. Precipitation and height above sea level is good in spatial.the model reflect characteristic of the theory of mountanious climatology effectively.
