In the context of garden cities, it is necessary to deeply explore the city’s mutual relationship between people and nature. Studying the supply and acquisition efficiency of community landscape ecosystem services can help analyze this relationship from the perspective of the flow of ecosystem service supply and demand and promote the precise improvement of inefficient spaces in ecosystem services. This study is based on evaluating community landscape ecosystem services and spatial clustering analysis, exploring the level of ecosystem services in different spaces. By coupling the evaluation results of ecosystem services and accessibility, explore the coupling and synergistic relationship between ecosystem service supply and acquisition efficiency. Finally, it explores the influence of key factors on the degree of coupling and synergy between the two through a random forest regression model. The results indicate that the comprehensive transition space’s community landscape comprehensive service index is relatively high, and the service heterogeneity is the highest among the three types of spaces, with strong plasticity. Ample green space often corresponds to a high degree of coupling and collaboration, while isolated small green space makes it challenging to provide an efficient service level. The partially enclosed green space structure with a complex shape improves the supply and acquisition efficiency of the community-scale ecosystem; NDVI has the highest importance and positive correlation for coupling collaboration, while residential building density and functional facility density are the opposite. According to the research results, this paper puts forward optimization strategies from three aspects: the importance, the structure, and the availability of service functions, aiming at providing a reference for the collaborative improvement of community landscape ecosystem service supply and acquisition efficiency in the context of garden cities.
