中小城市高铁新城地域空间效应与机制研究——以京沪高铁为例

快速城镇化背景下，凭借高铁的时空压缩及其扩散与集聚效应，高铁新城引发中国新城建设的热潮，高铁成为引导城市空间发展的重要因素，并且具有其他技术所不能比拟的空间效应。随着中国“八纵八横”高铁网络的进一步实施，未来将有越来越多的中小城市融入其中，如何更好的发挥高铁优势，通过高铁新城建设带动中小城市空间的可持续发展是亟待解决的问题。课题选取京沪高铁沿线的六个中小城市为案例，通过建立“社会—空间统一体”的理论分析框架，利用GIS技术构建不同时期城镇空间演化数据库。不仅对高铁新城内部的地域空间演化特征、过程与规律进行微观研究，而且还从城镇间“关系演变”的角度，建立引力模型、场强模型等分析城镇间的空间联系与组合特征，对区域城镇体系的空间重构效应进行宏观研究。一方面，通过构建多元多维的空间利益博弈模型，揭示高铁新城影响下的地域空间演化机制；另一方面也为我国中小城市高铁新城的建设实践提供规划和治理对策。

Under the background of rapid urbanization, relying on the compression and diffusion of high-speed railway and its agglomeration effect, high-speed rail has triggered the upsurge of new town construction in China. High-speed rail has become an important factor to lead to the urban spatial development , and has the spatial effect that other technologies cannot match.With the further implementation of Chinese "eight vertical eight horizontal" high-speed rail network, there will be more and more small and medium-sized cities integrated into it in the future. How to better give play to the high-speed rail, promote the sustainable development of the small and medium-sized cities through the metro rail construction is an urgent problem to be solved. The project takes six small and medium-sized cities along the Beijing-Shanghai high-speed railway as an example, establishing the theoretical analysis framework of "social space unity", to build the database of urban spatial evolutions in different periods through GIS.Not only do microscopic research on the internal metro rail regional spatial evolution characteristics, process and rules, but also establish the gravity model and field model to analyse spatial relationship and combination features between cities from the "relationship evolution" point of view and do macroscopic research on the reconstruction effect of urban system. On the one hand, we can reveal the mechanism of regional spatial evolution under the influence of high-speed rail new towns by constructing a multidimensional and multidimensional game model of spatial interests, on the other hand, we also provide planning and countermeasures for the construction of high-speed rail towns in small and medium-sized cities of China.
