摘 要 通过对全国(除港、澳、台)31个省域2000,2005,2010和2015年4个时间段城镇化、资源承载力以及环境支撑力三大子系统的耦合协调度进行测算与空间分析,得出:(1)2015年,各省耦合度范围在0.9~1.0之间,均处于城镇化与资源、环境发展的高耦合时期,说明我国城镇化在快速发展,资源与环境之间的互动关系也相对符合各区域发展的实际情况,总体状况良好.(2)2000—2015年,就整体而言,城市化-资源-环境的耦合度与协调度呈横躺的“S”型,先降后升再降,趋于稳定;就局部而言,各省三大子系统的综合发展指数演变格局是“东南沿海遥遥领先,黄土高原和云贵高原有待提升”.(3)低耦合协调区集中在我国西部地区,高耦合协调区集中在我国东南沿海地区,中度及以上耦合协调地区占的省份数量比相对较大.

Abstract Based on the measurement and spatial analysis from the coupling coordination degrees of three subsystems on urbanization, resource carrying capacity and environmental supporting power for 31 provinces in the years of 2000, 2005, 2010 and 2015, in this work, we show that: (1) The year of 2015 with the coupling degree between different provinces at the range of 0.9~1.0 was at the high coupling period of developments for urbanization,resources and environment, suggesting that during Chinas rapid urbanization process in this period of time,the interactive relationship between the resources and the environment is relatively consistent with the regional development, and, because of that, the overall situation is good. (2) From the year of 2000 to 2015, locally speaking, the comprehensive development index of the three subsystems possesses the evolution pattern that “the southeast coast is way ahead and the Loess Plateau and Yunnan Guizhou Plateau need to be improved”.Overall, the coordination coupling degree among urbanization, resource and environment can be expressed as alaid-down “S” shape, which increases first, then decrease, and, after that, increases again until it becomes stabilized. (3) The low coupling coordination area is concentrated in the western region of China, and the high coupling coordination area is concentrated in the southeast coastal area of China.

城市是人類文明的产物,也是人类利用和改造自然的集中体现.城镇化概念的提出最早可以追溯到1867年,由西班牙人Serda在其著作《城市化基本理论》中提出[1].城镇化最简单的含义就是“农(农业人口和农用土地)转非(非农业人口和城市用地)”的现象及过程.从18世纪的工业革命开始,大规模的集中生产和消费活动促进了人口的聚集,现代的交通和基础设施建设加快了城镇化的进程城,城镇化可以促进经济的繁荣和社会的进步,同时不可避免的影响了自然生态……
