都市成长区城镇空间多元组织模式研究

A Study on Urban Spatial Multi-pattern Development in the Growth Region of the Metropolitan Area

都市成长区城镇的发展具有复杂与动态的双重特征,本文在总结国内外相关研究的基础上,将大都市成长区城镇的空间结构与功能组织过程划分成四个阶段,即各城镇独立发展阶段、成长区培育阶段、成长区发展与扩张阶段和成长区创新发展阶段。研究以杭州市余杭区为例,从规模与结构两个角度对其所处的大都市区域化背景和自身发展特征进行解析,并对成长区城镇的发展趋势与路径进行研究,提出了网络化大都市区副城模式、创新极核与反磁力组团模式、文化创意与物流组团模式以及生态廊道与旅游组团模式四种城镇组群空间组织模式,并比较了四种模式各自特点和适用情况,最后总结了大都市成长区城镇空间组织必须着重把握的五个关系:与核心都市区之间的分工关系、与大都市人口动态变化之间的关系、与大都市经济区内外部联系通道的网络结构关系、文脉特质保护与构建都市区地域文化的关系、生态空间组织与都市区生态格局的耦合关系。

In the process of globalization, cities are drived into a pyramidal city system. The metropolises are the core of the global or regional economy, performing the management and control function. Against the background of globalization, urbans in the growth region of metropolitan area in China are facing not only many chances, but also some challenges. However, the urban development in the growth region of the metropolitan area is complicated and dynamic. Since the growth region is a part of the metropolitan area, its development should be coordinated with the metropolitan developing strategies, and make the best of its advantages, to define the direction of the industries, to position them correctly, and give the needed advices. Based on the international experience, this article classified the evolution of the spatial structure and functional system into four processes： urban independent development period, growth region incubating period, growth region developing and expanding period, and growth region innovative development period. This study selects the Yuhang Subarea as the case of study. It first analysed its regional background and its characteristics from scale and structure angles, and explored the development trend and trajectory of the growth region. Then, it put forward four spatial patterns of urban clusters： subcity model of metropolitan network, innovation core and anti-magnetic cluster model, cultural innovation and transportation cluster model, and ecological corridor and tourist cluster model. Consequently, it compared the characteristics and conditions of application of the four models. Finally, it concluded by summarizing five relationships in urban sptial development in the growth region of the metropolitan area： work division with core kernel metropolitan, correlations with the dynamic change of the metropolitan population, correlations with the network of metropolitan economic region, relationship between historical heritage protection and regional culture of the metropolitan area, and the coupling of ecological spatial network and regional ecological structure.
