基于“主体功能”的新型村镇建设模式优选及聚落体系重构——藉由“图底关系理论”的探索

新型村镇建设与主体功能区规划是分别针对我国当前阶段乡村发展、国土开发的重要空间调控手段,基于主体功能思维而对聚落体系进行自上而下的分类指导应该作为促进乡村聚落有序发展的重要思维。论文借助于图底关系理论,将主体功能区作为"均质面集"的发展意图转译到县级单元内"异质面集"的主导土地用途区,并进一步聚焦到"点集"乃至"点"层面的村镇聚落体系组织与聚落建设,总结了三类主体功能区的7种主导新型村镇建设模式及对应的空间优化目标,拓展了主体功能区规划在县级以下尺度的规划指导价值,实现了不同尺度空间规划的法则演绎,为主体功能区格局下我国县域尺度的村镇聚落功能优化与体系重构提供一种思路。

OPTIMAL MODELS OF NEW RURAL CONSTRUCTION AND SETTLEMENTS SYSTEM RECONSTRUCTION BASED ON REGIONAL MAJOR FUNCTION:AN EXPLORATION WITH THE AID OF FIGURE-GROUND THEORY

New rural construction and major function oriented zoning (MFOZ hereafter) are two important spatial regulation paths which are related to rural development and regional development respectively in China.The paper analyzes the connotation of regional major function and proposes its application in MFOZ, and illustrates the major functions and other functions among the three types of major functional zones involving spatial construction.Based on such analysis and with the aid of Figure-ground Theory, the study takes development elements which economic-development orientated functional zones put more emphasis on and which are carried by predominant land use zones divided in land-use planning as the Figure, and protection elements as the Ground relatively,while the patterns of ecology-protection types are just the reverse. Through logical deduction and induction, the paper summarizes seven dominant models and related requirements and objectives for new rural construction, that are placement model corresponding to development-optimized zone, polarization model corresponding to development-prioritized type and community model,renovation model, complementing model,demonstrating model and dissemination model corresponding to development restricted type.
