Research on the Coupled and Coordinated Development of Green Infrastructure and Urban Ecological Environment

Green infrastructure, as a nature-based solution, plays a key role in urban sustainable development. This paper focuses on the coupled and coordinated development of green infrastructure and urban ecological environment. It first defines the basic concepts of green infrastructure and urban ecological environment, and their interaction, establishing a theoretical framework for coupled and coordinated development and proposing an evaluation index system. Next, by analyzing the role of green infrastructure in improving the ecological environment, the paper explores its contribution to ecosystem services, urban climate resilience, and environmental governance. The study then uses the coupling coordination degree model and case study methods to evaluate the current status of green infrastructure construction and its coordination with ecological environment development in different cities, identifying key issues and challenges such as technological, policy, financial constraints, and ecological pressures brought about by urbanization. Finally, the paper suggests strategies for optimizing the construction of green infrastructure and its coordinated development with the ecological environment, including strengthening planning and policy guidance, improving multi-stakeholder collaborative governance mechanisms, and promoting green technological innovations to facilitate the sustainable development of urban ecological environments. The findings of this research can provide scientific evidence for urban planners and policymakers, promoting the rational layout and efficient application of green infrastructure in urban ecosystems.
