| 摘 要： | 以北京市2005年乡镇人均农业总产值和第一产业人口所占比重为指标变量,乡镇为基本单元,采用ES-DA的全局和局部空间自相关分析方法,包括Moran’sI指数、Moran散点图和LISA等,通过构造空间权重矩阵,从空间相互作用角度对2005年的北京市乡镇农业经济的空间分布进行研究和分析,揭示其空间相关性和空间异质性。结果显示,北京市乡镇农业经济的指标总体存在正的空间相关性特性,表现出很强的空间集聚特征,同时,结合Mo-ran散点图和LISA图像分析,揭示出局部乡镇存在空间异质问题。

| Abstract: | In this paper,in order to investigate the spatial characteristics of agricultural economy in Beijing,the authors take the agricultural total output value per capita and the primary industry population specific gravity in 2005 as index variables,and take the township as the basic analysis unit,and based on the global and local spatial autocorrelation methods of ESDA,including Moran I index,Moran scatter plot and LISA,with spatial weight matrix,research and analyze the agricultural economy spatial distributio... |
