摘要
根据气象台站最新30年的气候观测资料和台站地理信息,建立了南宁市主要气候要素的空间分析模型。在GIS的支持下,对无测站地区500 m×500 m网格单元上的气候要素值进行了推算,并利用反距离权重插值法进行残差订正,制作了南宁市农业气候资源的细网格立体分布图,分析了南宁市气候资源的特点及时空分布规律,为该市气候资源的合理开发利用提供了科学依据。
Based on the climatological data accumulated by stations in last 30 years and geographical information of the stations, the spatial analytical model of climatological elements for Nanning is built. By the support of GIS, the values of climatological elements in no-station regions are reckoned on the grids of 500 X 500 m,and the differences are revised by insertion method with anti-distance weight. The stereo and distributed map of Nanning agroclimatological resources on fine grid was drawn, and the features and distributing rules of the resources are studied. It provides a scientific basis for the reasonable exploitation and utilization of climatological resources of Nanning.
