通过对宜昌市城区公园服务水平建立耦合协调模型，来指导公园进行设计优化改造实践。在借鉴相关研究评价指标体系成果的基础上，结合《公园设计规范》，建立了生态服务、设施服务、文化服务3个指标层和20个评价因子，构建了耦合协调发展模型。依据评判标准对宜昌市的6个城区公园进行了耦合协调发展类型的划分，并分析出每个公园服务水平协调发展中的不协调指标。针对发展失调的世界和平公园，分析了其原因，提出了资源配置优化、展示设施更新、多方协作管理和功能分区细化4个方面的优化策略。

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.
