城市群地区城市高质量发展与生态环境的交互协同作用——以成渝城市群为例

高质量发展与生态环境交互作用的研究是实现可持续发展和建设美丽中国的关键议题。选取成渝地区36个市县为研究单元,以2005年、2010年、2015年和2018年为主要研究时间节点。基于可持续发展和美丽中国理念构建成渝城市群高质量发展评价指标体系,借鉴压力-状态-响应模型构建生态环境质量评价指标体系,应用熵权法测度城市高质量发展水平和生态环境质量水平;运用耦合协调度模型测度二者的耦合协调关系;利用地理探测器和社会网络分析法分析各因子交互作用类型及强度。结果表明：（1）成渝城市群城市高质量发展与生态环境耦合度高,交互影响作用显著;耦合协调水平较低,以低水平耦合协调为主,呈现明显的双核心空间结构。（2）城镇化与生态环境两系统间的因子交互作用强于各系统内部因子交互作用,系统间的因子交互作用呈现显著的非线性增强,系统内因子以双因子增强为主,系统间存在较强交互协同效应,各子系统交互作用存在明显的"涌现现象"和"蝴蝶效应"。（3）生态环境系统在与城镇系统的交互作用中发挥主导作用,生态环境水平、生态环境压力为关键交互因子;资源禀赋、生态保护、资源消耗、环境水平、创新力量、文化传承等为主要子因子。研究深刻解析成渝城市群城镇化与生态环境的交互协同模式,以期为成渝城市群的高质量发展提供科学参考。

Interaction between high-quality of urban development and ecological environment in urban agglomeration areas: Taking the Chengdu-Chongqing urban agglomeration as an example

Research on the interaction between high-quality development and ecological environment is the key issue in realizing sustainable development and building a beautiful China. According to the development status of urbanization high-quality development and ecological environment in Chengdu-Chongqing urban agglomeration including 36 research units of cities and counties, as well as the research results of relevant scholars, the years 2005, 2010, 2015, and 2018 were selected as the primary years of analysis. This paper constructs an evaluation index system for the high-quality development of Chengdu-Chongqing urban agglomeration based on the concept of sustainable development and the conviction of beautiful China. Building an ecological environmental quality evaluation index system by drawing on the pressure-state-response model and applying the entropy weight method to measure the level of high-quality urban development and the level of ecological environmental quality. The coupling coordination degree model is used to measure the coupling coordination relationship between the urbanization high-quality development system and the ecological environment system; Furthermore, the geographic detector and social network analysis method are used to analyzes the interaction type and interaction intensity of factors that consisting of three parts of research contents, which respectively are urbanization quality-ecological environment quality system and within their own system that they are urbanization high-quality development system and the ecological environment system. The results show that:(1) the highly coupled is proved in high-quality development and quality of ecological environment of Chengdu-Chongqing urban agglomeration and demonstrating significant interactive effects. At the same time, the coupling and coordination level between urban high-quality development and ecological environment quality is low, which is dominated by low-level coupling coordination, showing an obvious spatial development structure with Chengdu-Chongqing as the dual core. (2) During the study period, the factors interaction between urbanization high-quality development and ecological environment is stronger than that within each system. There is a strong interactive collaborative effect between the urbanization high-quality development and ecological environment. The internal factors of each system are mainly dual-factor enhancement. And the interaction of each subsystem has obvious "Emergence Phenomenon" and "Butterfly Effect". (3) The ecological environment system plays a leading role in the interaction with urban development in the primary years of analysis including the years 2005, 2010, 2015, and 2018. The result of the interaction strength of criterion layer shows that factors Ecological environment level and ecological environment pressure are the key leading interaction factors; Furthermore, resource endowment, ecological protection, resource consumption, environmental level, innovation force and cultural inheritance are major sub-factors in the he interaction strength of sub-criterion layer. This paper deeply dissects the interactive and cooperative mode of urbanization and ecological environment in Chengdu-Chongqing urban agglomeration. So as to provide a strong and sustainable scientific basis for Chengdu-Chongqing''s future high-quality development.
