大城市地域结构的反脆性机理探析

Study on the Antifragile Mechanism of Metropolitan Spatial Structure

大城市地域空间是城市区域的核心空间单元。在当前经济全球化的背景下,大城市地域空间结构优化既是全球化趋势的地域空间响应,也是国家整体战略转型的需要。而正处于转型期的大城市内功能重组和结构剧变正是导致城市脆性事件频发的关键原因。基于结构主义方法论,探究大城市地域结构“脆性”发生的传导机制,并提出脆性系统的三大层面,即要素脆性、结构脆性与环境脆性,为进一步反脆性大城市地域空间结构的构建和空间组织策略的提出奠定理论基础。

Metropolitan are the core component of the city-region.Under the background of economic globalization,the optimization of metropolitan spatial structure of is not only the response of regional space to the trend of globalization,but also the need of the overall strategic transformation of the country.The functional reorganization and structural upheaval in metropolitan in the transitional period are the key reasons for the frequent occurrence of urban fragile incidents.Based on structuralist methodology,this paper explores the transmission mechanism of brittleness in the regional structure of metropolitan,and puts forward three levels of brittleness system,namely factor fragility,structural fragility and environmental fragility,which will lay a theoretical foundation for the construction of spatial structure and spatial organization strategy of further antifragile metropolitan.
