摘要
城镇开发边界的划定与优化工作一直是国土空间规划改革的重要组成部分,其有助于遏制城市盲目扩张,促进资源结构有序重组。文章以武汉市为研究对象,从模拟角度探索城镇开发边界的划定与优化方法。考虑不同微观主体的偏好与目标,将多智能体模型(ABM)与元胞自动机(CA)耦合,初步划定城镇开发边界,在此基础上,引入基于博弈论的城市开发生态冲突耦合协调机制,实现划定结果的优化。研究表明:基于ABM的城镇开发边界划定方法可以深度刻画微观层面的智能体决策行为,且不同收入水平的居民智能体具有不同的偏好与目标;优化后城市用地面积为519.32 km2,新增城市用地主要集中在中心城区边缘,呈点状填充式扩展,且主城区外已出现了一定数量的卫星城,如黄陂前川、新洲邾城等。文章的研究从开发与保护的视角出发,旨在为国土空间开发格局优化提供参考。
The demarcation and optimization of urban development boundaries has consistently been a crucial element of territorial spatial planning reform.These practices are essential in preventing unchecked urban sprawl and in encouraging an orderly reorganization of resource structures.This research focuses on Wuhan city and delves into methodologies for the initial determination and subsequent optimization of urban development boundaries from a simulation perspective.Taking into account the preferences and goals of dif ferent micro-level entities,it couples the agent-based modeling(ABM) with cellular automaton(CA) to preliminarily delineate urban development boundary.On this basis,it introduces a coupling and coordination mechanism based on game theory for urban development and ecological conflict,aiming to optimize the delineation results.After simulation and optimization,the urban land area is 519.32 km~2.The newly added urban land is mainly concentrated at the periphery of the central city area,expanding in a scattered and infill manner.Moreover,a certain number of satellite cities have emerged outside the main urban area,such as Qianchuan street,Huangpi district and Zhucheng street,Xinzhou district.This paper starts from the perspective of development and protection,aiming to provide references for the optimization of land spatial development patterns.
