- Abstract:
-
It can provide reference for regional agricultural production and rational utilization of resources to explore the spatial distribution characteristics of temperature and precipitation and their influencing factors. The temperature and precipitation data of the China(Guizhou)ground yearly value data(1981—2010)was selected, the kriging, the inverse distance weight, and the spline, geographically weighted regression and other methods were used to explore the spatial distribution of temperature and precipitation of the Wujiang River Basin in Guizhou Province, and the impact of terrain on temperature and precipitation was analyzed. The results show that:(1)The temperature of the Wujiang River Basin in Guizhou Province is gradually increasing from the upstream(Hezhang-Shuicheng)to the downstream(Yanhe-Daozhen), and the temperature is roughly opposite to the change in altitude.(2)The precipitation is generally decreasing from the southeast(south)to the northwest, and there are more precipitations on the windward aspects such as Zhijin-Puding-Anshun.(3)The temperature and precipitation combination of the Wujiang River Basin in Guizhou Province is not balanced, and the area with good temperature and precipitation combination is less. The production and life should adapt to the temperature and precipitation.(4)The elevation of the Wujiang River Basin in Guizhou Province has the significantly negative impact on temperature, and when the altitude changes by 1 000 m, the temperature changes by 3.3~6.0℃. The impact degree is lower in the downstream, and it is higher in the upstream and lower in the middle.(5)The spatial difference of precipitation of the Wujiang River Basin in Guizhou Province is large, and the space effects simulated by the geographically weighted regression are positive or negative. The space effects are negative in upstream of the basin, these are positive in the middle reaches of the basin.
