【摘要】 城市土地集约利用与生态文明建设存在交互耦合关系,评价二者的耦合协调程度对提高城市土地利用效率、促进城市可持续发展具有重要意义。以五大国家级城市群(长江三角洲、珠江三角洲、京津冀、长江中游和成渝城市群)为研究对象,利用加权TOPSIS模型分别评价2007-2016年土地集约利用与生态文明建设子系统综合评分,在此基础上,借助耦合协调度模型测算两者耦合协调度及演变。结果发现:2007-2016年五大城市群城市土地集约利用与生态文明建设综合评分均呈上升趋势,城市群间差别较小;二者耦合协调度由中度失调向基本协调转变,整体达到基本协调水平,城市群耦合协调度均值从大到小依次为珠江三角洲城市群、长江三角洲城市群、京津冀城市群、长江中游城市群、成渝城市群。可见,进一步加强土地资源管理、深化城市生态环境综合治理,可以促进城市群土地集约利用与生态文明建设良好协调发展,推动建设资源节约型、环境友好型社会。图1表2参16更多还原

【Abstract】 There is an interactive coupling relationship between urban land intensive use and ecological civilization construction. It is important to evaluate the degree of coupling and coordination of urban land use efficiency and urban sustainable development. Taking China’s five national-level urban agglomerations including Yangtze River Delta Urban Agglomeration, Pearl River Delta Urban Agglomeration, Beijing-Tianjin-Hebei Urban Agglomeration, Yangtze River Middle Reach Urban Agglomeration and Chengdu-Chongqing Urban Agglomeration as research objects, the weighted TOPSIS model is used to evaluate the comprehensive scores of the intensive use of land and ecological civilization from 2007 to 2016. On the basis of this, the coupling coordination degree model is used to measure the coupling coordination degree and evolution. The study found that the comprehensive scores of land intensive use and ecological civilization construction of the five national-level urban agglomerations had been on the rise from 2007 to 2016, and the differences among urban agglomerations were small; the coupling degree between urban land intensive use and ecological civilization construction changed from moderate disorder to basic coordination, and reached an overall coordination level. The average coupling coordination degrees of urban agglomerations were ranked as follows: Pearl River Delta > Yangtze River Delta > Beijing-Tianjin-Hebei > Yangtze River Middle Reaches > Chengdu-Chongqing. Further strengthening the management of land resources and deepening the comprehensive management of urban ecological environment can promote the coordinated development of land intensive use and ecological civilization construction of urban agglomerations, and promote the construction of a resource-saving and environmentfriendly society.
