基于经济密度差异特征的区域空间结构研究--以江西省为例

Defining Regional Spatial Structure with Economic Density Measures: A Case Study of Jiangxi Province

通过引入因子分析法和聚类分析法,基于江西省91个地理单元的18个经济密度指标,对江西省经济密度的地域空间分布进行研究,结果表明:非农产业的空间经济密度、非农产业的人均经济密度和农业的经济密度是影响江西省经济密度的三大因子;按照经济密度差异,江西省可划分为4种类型区域,不同类型区域的地理单元组成3种城市群空间结构类型,分别为扇形结构、双核心结构和飞地型结构;江西省初步形成了沿浙赣线和京九线发展的"十"字形空间结构格局。

A study on the 91 geographic areas and an analysis of each with a system of 18 different indices shows that non-agricultural spatial economic density, non-agricultural economic density per capita, and agricultural economic density are the three major factors affecting Jiangxi provincial economic density. Three geographic categories are derived： fan, dual core, and enclave; and the province is categorized into four levels of economic density. Preliminary spatial structures along the Zhegan and Jingjiu rail corridors have been developed.
