中国城镇用地扩展时空异质性研究进展
发布时间：2018-12-11 03:42
【摘要】：城市扩展是城镇化对土地覆被变化影响的响应,其动态过程具有典型的时空异质性特征,21世纪以来我国的快速城镇化进程为全球城市研究提供了良好素材与实证地域。该文紧扣城市扩展的时空异质性特征,从过程格局和驱动机制两方面对已有文献进行梳理与总结,并展望未来研究重点与方向,以期为解决中国城市扩展的现实问题以及践行健康城市化之路提供参考。研究表明:1)在过程格局方面,区域尺度研究关注国家及地区在不同时期城镇用地扩展的数量特征,个案尺度研究则关注城市扩展的空间异质性,研究对象以东、中部大城市为主,遥感与GIS空间分析是其主要的数据源与技术手段;2)在驱动机制方面,外部机制研究充分讨论经济发展、人口增长等社会经济因素对城镇用地总量增长的影响,内部机制则是城市扩展空间异质性产生的动因,旨在从微观层面揭示影响城镇用地转变的各类地理区位因子;3)未来应注重发展结合中国城镇化实际的理论分析框架,加强对小尺度区域及城市扩展重点、热点区域的研究,并不断突破均质地域假设,探讨城市扩展影响因素作用效应的空间异质性特征。
[Abstract]:Urban expansion is the response of urbanization to land cover change, and its dynamic process has typical space-time heterogeneity characteristics. The rapid urbanization process in China since the 21st century has provided good materials and empirical areas for global urban research. Based on the characteristics of spatial and temporal heterogeneity of urban expansion, this paper reviews and summarizes the existing literatures from two aspects of process pattern and driving mechanism, and looks forward to the focus and direction of future research. In order to solve the practical problems of urban expansion in China and practice the road of healthy urbanization. The results show that: 1) in the process pattern, regional scale studies focus on the quantitative characteristics of urban land expansion in different periods of time, while case scale studies focus on the spatial heterogeneity of urban expansion, to the east of the study object. Remote sensing and GIS spatial analysis are the main data sources and technical means. 2) in the aspect of driving mechanism, the influence of social and economic factors such as economic development, population growth and other social and economic factors on the total increase of urban land use is fully discussed, while the internal mechanism is the cause of the spatial heterogeneity of urban expansion. The purpose of this paper is to reveal all kinds of geographical location factors that affect urban land use transformation from the micro level. 3) in the future, we should pay attention to the development of the theoretical analysis framework combined with the reality of urbanization in China, strengthen the research on small scale regions and urban expansion, hot spots, and break through the hypothesis of homogeneous region. This paper discusses the spatial heterogeneity of the effect of factors affecting urban expansion.
