摘要
城市蔓延问题已成为中国城市可持续发展的绊脚石,认识和探讨中国城市蔓延的时空格局与影响因素,对调控城市蔓延态势、优化城市人地关系、促进城市健康发展具有重要意义。文章采用城市蔓延指数分析全国278个城市市辖区2002—2017年的蔓延状况,结合变异系数、Theil指数和热点分析阐述中国城市蔓延的时空分布特征与区域差异,基于地理探测器探讨影响城市蔓延的主要因素,为治理中国城市蔓延问题提供对策启示。结果表明:(1)中国绝大部分城市处于中低度蔓延状态,蔓延态势呈现了"低—高—低"的演变过程,人口负增长型蔓延有向全国扩散化发展的趋势;(2)城市蔓延的区域差异显著,中西部地区城市蔓延态势较东部地区更为严峻,中小城市蔓延态势较大城市更为严峻;(3)经济发展维度对全国和中西部地区城市蔓延影响较大,而东部地区城市蔓延受经济发展和社会文化两者共同作用。
The problem of urban sprawl has become an obstacle to the sustainable development of many cities in China.Understanding and exploring the spatiotemporal pattern and influencing factors of urban sprawl in China is of great significance for controlling urban sprawl,optimizing urban human-land interactions and promoting urban sustainable development.This paper uses methods such as Urban Sprawl Index and Geodetector to analyze of the urban sprawl in278 cities of China.This paper also expounds the spatiotemporal pattern characteristics and regional differences of urban sprawl in China,and discusses the main factors affecting the urban sprawl in China.The results show that:1)Most Chinese cities are in a state of moderate to low sprawl.The sprawl of the situation shows the evolution of"low-high-low",and the sprawl with negative population growth has a tendency to spread to the whole country.2)It has significant regional differences in urban sprawl:the central and western regions are more serious than the eastern regions,small and medium cities are more serious than large cities.3)The dimension of economic development has a greater impact on urban sprawl in the whole country,as well as the central and western regions,while urban sprawl in the eastern region is affected by both economic development and social culture dimension.
