淮海经济区社会经济发展的空间格局分析

基于县域图形数据和社会经济统计数据,运用GIS的空间插值和叠置分析技术,对淮海经济区城镇及人口密度的空间分布、社会经济发展的空间格局特征进行了分析;结果表明,淮海经济区城镇、人口较为密集,出现了明显的城镇密集带和人口集聚中心;区域发展的整体水平较低,社会经济发展的空间分异明显,苏北、鲁南社会经济发展水平明显高于豫东和皖北地区;通过对该区社会经济发展的综合评价进行空间聚类,将其划分为4个类型区:苏北鲁南片区、鲁中片区、皖北周口片区、豫东鲁西南片区;在概括各类型区的社会经济特征的基础上,提出了各区的发展对策.

Analysis of spatial pattern for development in Huaihai Economic Region

Based on country map and social economic statistic data,the paper analyzed the spatial distribution of town and population,and the characteristics of the spatial pattern of society economic development,using GIS technology of spatial interpolation and overlay analysis.The result indicated that:in Huaihai Economic Region,the town and the population distributed concentratively,town agglomeration and population gathering center appeared;the level of overall development in society economic is low,and has an obvious spatial differentiation,social economic development level in the northern Jiangsu and the southern Shandong areas is higher than in the northern Anhui and eastern Henan areas.Then,k-means,clustering algorithm is performed to cluster the component scores in society economic development into four typical regions:the northern Jiangsu and the southern Shandong area,the middle part of Shandong area,the northern Anhui and Zhoukou area,the eastern Henan and the southwestern Shandong area.Then,it put forward development countermeasures to each region,on the basis of generalization of social and economic characteristics.
