Characteristics of Jiangxi Province Temperature Spatial Distribution and Influence on Agriculture
The study of the spatial distribution characteristics is of great significance to the high-quality development of its agricultural economy.Jiangxi provincial meteorological stations were selected to spatially interpolation the annual average temperature,annual average highest temperature and annual average lowest temperature from 1981 to 2010 by using the ordinary gin interpolation method,and then the accuracy of the interpolation results was tested.Furthermore,combined with the DEM,the spatial distribution of air temperature in Jiangxi Province was analyzed.The results show that the annual average temperature,annual highest temperature and annual lowest temperature in Jiangxi Province are generally affected by latitude,and local topography and cold wave.Latitude,altitude and cold wave have become the main factors affecting low temperature.Finally,the influence of temperature distribution characteristics on agricultural layout,crops and agricultural development is expounded.
