摘要:城镇化与生态环境之间是相互联系和促进的唇齿关系，其耦合协调程度对实现地区高质量发展和可持续发展具有重大影响。将物理学中的"耦合"概念引入城镇化与生态环境耦合协调研究中，建立了耦合协调度模型，并构建了城镇化与生态环境耦合协调度评价指标体系和耦合协调度基本类型划分体系，分析了2010-2018年武陵山片区六个中心城市城镇化与生态环境耦合协调度的时空分异。结果表明：（1）各中心城市的耦合协调基础较好，且呈现出良好的发展态势。（2）各中心城市的空间差异明显，2010年、2015年与2018年六个中心城市城镇化与生态环境耦合协调发展内部差异性较大，东部大于西部，怀化市"单核"特征明显。（3）武陵山片区城镇化与生态环境耦合协调度没有实现突破性、跨越式的提升，且城镇化滞后的问题较为明显，影响了两者实现高耦合协调度的进程。研究认为须要坚持以绿色为底色，以生态为引领，加快提升武陵山片区城镇化发展水平，走出一条绿色生态的城镇化高质量发展新路。



Abstract:Urbanization and eco-environment is closely related and mutually dependent, and the degree of coupling coordination between urbanization and eco-environment has a great impact on the realization of high-quality development and sustainable development in the region. This paper introduces the concept of coupling in physics to coupling coordination of urbanization and eco-environment in the study, then builds the comprehensive evaluation model, the coupling model, the coordinated development model and coupling coordination degree model. To value the comprehensive degree, it also structures the degree index system of coupling coordination and presents basic classification degree system of coupling coordination. Based on these, this paper analyzes the evolution of time and space of coupling coordination between urbanization and eco-environment of six central cities in Wuling Mountain area from 2010 to 2018. The results show that: (1) the coupling coordination foundation of each central city and the trendency of coupling coordination development is good. (2) There are obviously spatial differences among the central cities. The gap between coupling and the coordinated development of urbanization and eco-environment among the six central cities are distinct. The eastern part is greater than the western part, and meanwhile an obvious "single core" characteristic exists in Huaihua. (3) There is no breakthrough and leap-type improvement in the coupling coordination degree between urbanization and eco-environment in Wuling Mountain area. The lagging urbanization is an obvious problem, which hinders the process of improvement in the coupling coordination degree. It is suggested to accelerate the improvement of urbanization development level in Wuling Mountain area with green and ecological principles, and strive to find a new road of high-quality urbanization development of green ecology.
