基于GIS的广安市脐橙气候适应性区划

GIS-Based Study on the Climatic Adaptability Division of Navel Orange of Guangan, Sichuan Province

将常规地面观测资料和山地剖面气象观测、气象哨点观测资料相结合 ,建立广安市脐橙气候适应性指标要素的细网格推算模型 y=f(h ,Ψ ,l,β) ,应用 1∶2 50 0 0 0地理信息资料和GIS技术将广安市脐橙生产划分为四类区域 ,其结果指出了广安市脐橙生产布局中的问题 。

With the eco-climatic adaptability data, the growth laws and indexes of navel orange in Guangan, Sichan Province are studied. And the distribution model of climatic factors is established, i.e. y=f(h,Ψ,l,β).Then based on the GIS data of 1∶250000 and GIS technique, the climatic division of Guangan navel orange production is made. The result shows that climatic condition in some sub-area is not adaptive to the navel orange production.
