主 题:Sichuan Province precipitation geostatistics temporal-spatial variation
摘 要:Precipitation is a key factor in the water *** the same time,precipitation is the focus of study in meteorology and climatology,ecological environmental assessment,non-point source pollution and so *** the temporal-spatial variation and the corresponding factors of precipitation has become the object of hydrology and *** on the annual precipitation data,we analyzed the spatial distribution of precipitation in Sichuan Province in China as well as the temporal-spatial variation and the corresponding influence factors *** results show that the amount of precipitation was abundant,but the spatial distribution was not consistent with it and the amount of precipitation gradually declined from the south-east to the north-west in Sichuan Province,***,the spatial distribution was different throughout the *** result of correlation analysis indicated that elevation,temperature and air pressure were three key factors affecting the amount and distribution of precipitation,and the correlation coefficients were 20.56,0.38 and 0.45 ***,the relationship between the slope of topography and precipitation were significantly negative and the average correlation coefficient was 20.28.
