中部地区2000—2020年城市收缩的特征及影响因素分析

Analysis on the Characteristics and Influencing Factors of Urban Shrinkage in Central China From 2000 to 2020

近年来,城市收缩问题在全球范围内引起广泛关注,在中国也日益明显。文章利用2000年、2010年和2020年三次人口普查数据,在地级市尺度上分析中部地区2000—2010年和2010—2020年两个时期城市收缩的空间特征及演化趋势,并定量分析了其形成与演化的影响因素,结果表明:(1)从整体趋势来看,中部地区存在明显的城市收缩现象、且呈现出区域性演化趋势;(2)从空间形态上,2000—2010年以大面积扩张为主要特征,湖北省最为明显。2010—2020年形成以省会城市为中心的环状收缩的特征;(3)产业发展质量、经济发展水平与城镇化等因素对城市收缩的影响显著,且经济因素的重要程度逐渐超过产业发展。

In recent years,the problem of urban shrinkage has attracted widespread attention around the world and has become increasingly obvious in China.Using the three census data of 2000,2010 and 2020,this paper analyzes the spatial characteristics and evolution trends of urban shrinkage in the central region from 2000 to 2010 and 2010 to 2020 at the prefecture-level city scale,and quantitatively analyzes the influencing factors of its formation and evolution,the results show that:(1)in terms of the overall trend,there is obvious urban shrinkage in the central region,and there is a regional evolution trend;(2)in terms of spatial form,from 2000 to 2010,largescale expansion was the main feature,and Hubei Province was the most obvious.From 2010 to 2020,the characteristics of circular contraction centered on provincial capitals were formed;(3)the quality of industrial development,the level of economic development and urbanization have a significant impact on urban shrinkage,and the importance of economic factors gradually exceeds that of industrial development.
