基于多情景模拟的武汉市空间结构形态研究

A SPATIAL STRUCTURE STUDY BASED ON MULTI-SCENARIO SIMULATION

武汉历史悠久、人文荟苹,两江交汇、三镇鼎立,湖群密布、河网纵横,呈现出空间碎片化、多样化的特征,也决定了城市空间形态的多元化、复杂性。本文系统回顾了武汉历轮城市总体规划的空间结构,深入剖析了历史空间演变特征与城市发展动力机制,进而识别出影响城市空间结构的核心要素;从“关注人、关注城市-区域、关注自然”的角度出发,基于人的中微观尺度空间、现状空间分级特征、武汉大都市区、廊道一轴带理论等方面,通过多情景模拟方法分析了城市空间结构与发展模式,构建了适合武汉未来发展的“1331”城市空间结构方案,为转型发展背景下的新一轮总体规划编制工作奠定基础。

Wuhan has a long history and a galaxy of advanced culture and talents.It is located at the confluence of the Hanjiang River and Yangtze River and consists of three adjacent towns,with lakes and rivers all around.The space presents fragmented and diversified characteristics,and it leads to the complexity of urban spatial form.This paper systematically reviews the spatial structure of Wuhan urban master plans in each period,and analyzes the characteristics of Wnhan's historical spatial evolution and the development dynamic mechanism,and identifies the core elements affecting the urban spatial structure.Focused on the people,the city-region,and the nature,based on the medium-micro spatial scale,the classification of the current space,the metropolitan area of Wuhan,the corridor axis-belt theory,etc.,this paper analyzes the urban spatial structure and development mode through multi-scenario stimulation,and puts forward a "1331"urban spatial structure adapting to future development as well as laying foundation for the new round of master plan compilation under the background of transformation and development.
