摘要
探讨城市空间"三生"功能之间的互动关系,是新型城镇化推进中城市空间优化、高质量发展亟待解决的关键.以"三生"理论为基础,运用空间分析法、耦合协调模型和地理探测模型方法,研究2009～2019年长江经济带城市空间"三生"功能耦合协调时空特征及影响因素.研究得出:(1)长江经济带城市空间"三生"功能耦合协调水平呈现倒"U"型逐步趋于波动平稳发展的态势;(2)城市空间"三生"功能耦合协调水平存在明显的空间分异,呈"东高西低"的格局,高值主要集中在长三角、长江中游和成渝城市群,并且以省会城市为中心向周围梯度递减;(3)影响城市空间"三生"功能耦合协调发展的主导因素为经济发展水平、城镇化水平和环境治理水平,且存在空间差异.研究认为:应充分发挥中心城市的"极化作用"优势及其空间溢出效应,促进城市空间"三生"功能耦合协调发展.研究结果可以为城市空间优化、区域高质量协调发展提供依据.
Abstract
The purpose of this paper was to probe into spatio-temporal evolution characteristics and influencing factors of production-living-ecological functions(PLEFs)of urban space to improve urban high-quality development.A coupled coordination degree model,spatial analysis method and geographic detection model were employed.The study area was the Yangtze River Economic Belt.The results showed that:(1)On the whole,the coupling and coordination level of urban space PLEFs showed a trend of"inverted U",implying agradual development in to fluctuations and stability;(2)There was obvious spatial differentiation in the coupling and coordination level of the PLEFs,showing a pattern of"high in the east and low in the west",and the areas with high coupling and coordination levels were mainly concentrated in the Yangtze River Delta,the middle reaches of the Yangtze River and the Chengdu-Chongqing urban agglomeration,with a gradient of decreasing towards the surrounding areas centered atprovincial capitals;(3)The dominant factors affecting the coupling and coordinated development of PLEFs were the level of economic development,urbanization and environmental governance.This study suggested that the advantages of the"polarization effect"of central cities and their spatial spillover effects be given full attention to promote the coupling and coordinated development.The results can provid a basis for urban space optimization and regional high-quality coordinated development.
