县域村镇空间结构特征分析——以金湖县为例

Characteristic Analysis of County and Rural Spatial Structure—A Case of Jinhu County in Jiangsu Province,China

综述了县域村镇空间结构的内涵,指出村镇空间结构节点、通道、域面和流这4种要素的空间排列及其相互作用构成了相应的村镇空间结构。概述了县域村镇相关理论进展,指出目前区域空间结构的研究理论主要集中在宏观地域或城市空间,对县域特别是微观村镇空间结构的研究还比较少见。在此基础上,介绍了区域空间结构的4种理论模式及其特征,结合4种要素构建了村镇结构要素分析指标体系,并以江苏省金湖县为例进行了村镇空间结构分析。结果表明,金湖县村镇空间结构目前仍处于极核式发展阶段,村镇体系不完善,基础设施网络通络通道未成体系,县域经济呈现规模不经济;金湖县城镇之间空间关联程度、空间相互作用程度较弱;该研究的空间结构特征分析模式能够比较客观地反映出研究区域的空间结构特征。

This thesis gives overview of the connotation of rural spatial structure,indicating 4 kinds of elements,namely nodus,passage,region and flow.Their spatial arrangement and interaction lead to the corresponding rural spatial structure.This thesis also offers panorama of the related theoretical progress of intra-county and rural areas,indicating that the research theories of regional spatial structure at present,mainly focus on macroscopic region or urban space,but there is shortage of researches on county spatial structure,especially microscopic rural spatial structure.On such basis,4 kinds of theoretical models and characteristics of regional spatial structure have been introduced.We build analysis index system of rural structural elements on the basis of 4 elements,and conduct rural spatial structural analysis,taking Jinhu County as an example.The result shows that rural spatial structure in Jinhu County is still at stage of nucleus-cluster development and rural system is not so sound.In addition,the passage network system of infrastructure has not taken shape,and county economy presents diseconomy of scale.The spatial interaction and association among towns in Jinhu County are weak.The characteristic analysis model of spatial structure in this research can objectively reflect regional characteristic of spatial structure.
