摘要
年均气温空间分布特征对农业高质量发展具有重要意义.选取江西省气象站台数据,使用普通克里金插值法对1981-2010年的年均气温、年均最高气温、年均最低气温分别进行空间插值,并检验插值结果精度.在此基础上,结合DEM,分析研究江西省气温在空间上的分布特征.结果表明:江西省年均气温、年均最高气温、年均最低气温总体受纬度影响,局部受到地形和寒潮的影响,纬度、海拔与寒潮成为低温的主要影响因素.最后,阐述了气温分布特征对农业布局、农作物生长、农业发展等方面的影响.
Abstract
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.
