基于空间自相关的乡镇经济差异分析

Research on Spatial Variability of Towns Based on the Spatial Autocorrelation

应用GIS和空间自相关分析技术,对2006年瓦房店市27个乡镇的GDP数据的空间差异进行研究,揭示了瓦房店市乡镇经济的空间自相关和集聚特征。研究表明,瓦房店市各乡镇GDP数据存在空间相关性,有明显的空间集聚;Moran散点图多位于第三、四象限,高低集聚、低低集聚较多,显示出经济发展的不平衡;市中心及沿海地区经济较发达,而北部内陆地区经济发展缓慢,应加大对北部乡镇的经济扶持力度。

Using 27 towns in Wafangdian city as study unit,through the GDP index of each town in 2006,this paper studied on spatial variability of towns in Wafangdian city based on GIS and spatial autocorrelation,which revealed the spatial characteristics of towns' economy.The results show that the towns' GDP index exist the spatial correlation,and have obvious spatial agglomeration.Most Moran scatters are in the third and fourth quadrant.The city center and coastal areas are more developed,on the contrary the northern inland regional is slow.So the government should strengthen the support for the northern towns’ economy.
