Abstract:A coupled coordination model is established for the service level of parks in the urban area of Yichang City to guide the parks in carrying out design optimization and transformation practices. Based on the results of the related evaluation index system research, combined with Code for the Design of Public Park, three index layers of ecological services, facility services and cultural services and 20 evaluation factors are established to construct a coupled and coordinated development model. Based on the evaluation criteria, the six urban parks in Yichang City are divided into coupled coordinated development types, and the indicators of dissonance in the coordinated development of each park's service level are analyzed. The reasons for the dysfunctional effect of the World Peace Park are analyzed, and optimization strategies are proposed in four aspects: optimization of resource allocation, updating of display facilities, multi-party collaborative management, and refinement of functional zoning.
