Examination of a coupling coordination relationship between urbanization and the eco-environment: Case study of Hangzhou

摘要：为了探索城市化与生态环境之间的耦合协调关系，以杭州市为研究对象，构建了城市化与生态环境评价指标体系，并利用耦合协调度模型，定量分析了杭州市2003-2016年城市化与生态环境的发展水平状况和两者之间的耦合协调关系及变化趋势.结果表明：经济城市化和生态环境压力分别对城市化子系统和生态环境子系统的贡献份额最大；耦合协调度受城市化子系统和生态环境子系统贡献份额比例（α/β）的影响很小，受城市化子系统与生态环境子系统的综合发展水平的影响较大；城市化与生态环境的耦合协调类型由"基本不协调-城市化滞后"发展到"高度协调-城市化滞后"，再发展到"高度协调-生态环境滞后"阶段.在城市化快速发展的驱动下，生态环境滞后的问题凸显.因此，在研究制定城市化发展战略时应重点关注城市化过程中对生态环境的影响，以改善生态环境质量，实现两者协调发展.

Abstract：In order to understand the coupling and coordination relationship between urbanization and eco-environment, we took the city of Hangzhou as an example and evaluated quantitatively evolution of the relationship between urbanization and the eco-environment development during 2003-2016, by establishing the assessment indicator system and applying it to the coupling coordination model. The results show that:①economic urbanization and eco-environment pressure make the greatest contributions to the urbanization subsystem and the eco-environment subsystem, respectively;②compared with the comprehensive development level subsystems, the ratio between α-urbanization and β-eco-environment has little influence on the coupling coordination system; ③the coupling coordination degree evolved from the stage of "unbalanced development with hindered urbanization" to "superiorly balanced development with lagging urbanization", and then to a stage of "superiorly balanced development with a lagging eco-environment". The problem of lagging eco-environment is severe due to the rapid development of urbanization. Results from this study therefore suggest that the adverse pressure of urbanization on eco-environment deserves more attention when design and implement the urbanization strategies.
