基于LBS数据的大都市远郊新城区城镇化特征研究——以南京溧水中心城区为例

Understanding the Characteristics of Urbanization of Suburban New Town in Metropolis through LBS Data: A Case Study of Lishui Central City, Nanjing

以大都市区一体化发展背景下南京溧水中心城区为例,使用LBS数据,从职住关系、人地关系、交通公平3个维度解析了大都市远郊新城区的城镇化特征,并探讨了未来发展趋势。研究表明:(1)溧水中心城区的产业区、新区和老城区之间呈现空间发散与弱关联特征,加之受到南京主城的牵引,造成了其城镇化时空格局的紊乱;(2)大都市远郊新城区城镇化的动力机制正从被动扩容转向综合多元,城镇化的空间模式正从拼贴混杂转向缝合提升。研究认为,大都市远郊新城区的发展出现新动能与新路径,但如何治理和应对快速城镇化阶段导致的紊乱问题仍然是其面临的主要挑战。

Amidst the backdrop of integration development in the metropolitan area,this article aims to analyze the urbanization characteristics of the suburban new town through examining the case of Lishui central city,Nanjing.Using multi-source LBS data,the article conducts quantitative analysis from three dimensions including the jobs-housing relationship,people-land relationship,and traffic equality.On this basis,the development trend of the suburban new town is discussed.There are two major findings reported as followed:① The spatial dispersion and weak correlation between the industrial area,new city,and old downtown of Lishui central city,coupled with the pull of Nanjing central city,have caused the disorder of spatial and temporal pattern of its urbanization process.② The mechanism of urbanization in the suburban new town in the metropolitan area is shifting from passive expansion to comprehensive diversification,and the spatial pattern of urbanization is shifting from fragment and mixture to integrating and upgrading.Accordingly,this article concludes that though there are new driving forces and paths for the development of the suburban new town,addressing the disorder caused by rapid urbanization is still the main challenge.
