不同历史时期特殊事件影响下的城市空间结构演变研究——以天津市为例

City Spatial Structure Evolution Affected by Special Events in Different Historical Periods:A Case Study of Tianjin

通过构建"不同历史时期特殊事件-城市空间结构"研究模式,以天津市为案例,把影响城市空间发展的要素与城市空间结构有机结合起来,解释城市空间结构演变的动力机制。以特殊事件为切入点,首先把影响天津城市空间演变的特殊事件分为七大要素:突发事件、经济政策、城市方针、城市规划、基础设施建设、土地制度和住房制度,这些要素决定了天津城市的经济发展、产业构成、城市发展规模、城市布局、空间发展走向以及城市土地利用效率和住宅类型与分布;然后通过分析各要素里的重大事件对天津城市空间演变的影响,找出各重大事件在天津城市空间结构演变中所扮演的角色,以期达到二者有机的统一。最后在此基础上,对未来天津城市空间结构的发展做了预测。

Urban spatial structure is a hot topic in the urban geography and urban economy research. Theoretically, the evolution and mechanism of the urban spatial structure is affected by multiple factors, such as competition, rental, governor and relations of production, et al. Chinese scholars usually focus on the single factor influence in the urban spatial structure evolution and mechanism studies, and the connection between the factors and spatial has been ignored. Thus, according to reconstructing the model of 'special events', logically combining the urban spatial structure and factors affecting the urban development to understand the dynamic mechanism of the spatial structure evolution of Tianjin City in this article. Special event is the breakthrough point.Firstly, classifying the special events in different historical periods of spatial evolution in Tianjin into seven factors: spatial event, economy policy, urban development policy, urban planning, infrastructure, land system and housing system. They decide the economic development, industrial structure, urban development scale, urban distribution, spatial development trend, land use efficiency and house estate type and distribution, respectively.Secondly, according to the analyze the influence of special event in different historical periods to Tianjin spatial evolution in each factor, figured out the role of special events in the Tianjin spatial structure evolution. Finally, the development of Tianjin spatial structure in the future was predicted.
