- Abstract:
- The geographical environment of the Yunnan-Guizhou Plateau is complicated, and the spatial differences between temperature and precipitation are significant. It is of great significance to study the spatial distribution characteristics of temperature and precipitation. Based on the average temperature and precipitation data of 180 meteorological stations in the Yunnan-Guizhou Plateau from 1981 to 2010, the Kriging method, inverse distance weight method, and spline function method were used to investigate the spatial distribution characteristics of temperature and precipitation and their influencing factors. The results show that:(1)the spatial distribution of air temperature in the Yunnan-Guizhou Plateau was generally higher in the south and lower in the north, and the temperature in the Umeng Mountains and Hengduan Mountains in northwestern Yunnan was relatively low;(2)the spatial distribution of precipitation in the Yunnan-Guizhou Plateau was generally higher in southern Yunnan, and there was relatively less precipitation in northeast Yunnan and northwestern Guizhou; precipitation was significantly affected by topography in some areas;(3)among the various interpolation average percentage errors of temperature and precipitation distribution in the Yunnan-Guizhou Plateau, the errors decreased in the order: SPLINE>TREND>OK>KED>IDW(precipitation), SPLINE>TREND>IDW>KED>OK(temperature), temperature OK, the precipitation IDW interpolation accuracy was high and the effect was good;(4)for every 1 000 m elevation rise in the Yunnan-Guizhou Plateau, the temperature decreased from 6.2 to 3.3℃; The altitude along the Ailao Mountain(Wuliang Mountain)-Hengduan Mountain had a higher degree of influence on temperature, but the effect of altitude on precipitation was relatively complicated.
