地方级中心城市的市域空间结构是全面反映城乡关系特征的空间尺度,也是体现中国城乡二元结构的基本尺度。因此,地方级区域空间结构重组的主要内容就是以协调城乡关系为主线展开的,在现代城乡关系理论的指导下,通过构建新的产业关系、优化区域城镇空间关系和等级规模结构、优化城乡通道系统、理顺城乡"流"动、探索新的城乡空间结构模式等措施,从而建立起符合区域发展实际和宏观社会经济发展大背景的城乡空间结构。以衡阳市为实证,论述了基于城乡互动的市域空间结构重组的具体途径与措施。

The spatial structure of local urban area is a spatial scale giving fully expression to relations features between urban and rural area, also a basic scale reflecting economy of urban and rural area. So the main cotents of spatial structure reorganization of locational scale are spreaded according to coordination of relations between urban and rural area. Judging by the modern theory of relations between urban and rural area, through setting up new industry relations, optimizing space and rankscale structures of urban system, optimizing passages system of urban and rural areas, putting "flows" in good order, exploring new spatial structure model of town and countryside relations, etc., a new spatial structure of town area coinciding with the reality of area development and the background of macroscopic society and economy should be set up. With Hengyang City as a case study, this paper discusses some concrete methods and steps reorganizing spatial structure of town area based on interaction between towns and countrysides.
