As a global metropolis, Shanghai has a high population density and limited land resources. Optimizing existing land and addressing resource imbalances have become major challenges for urban development. Correspondingly, pocket parks, as micro green spaces in cities, play an important role in balancing the demand for public resources in urban green spaces and improving ecological benefits. Taking multiple pocket parks in the main urban area of Shanghai Lingang as the research object, this paper explores and analyzes the main problems of unreasonable spatial layout, low population adaptability, and low planting quality, proposes solutions, and explores the interaction and chain effect between the spatial creation and plant configuration of pocket parks in the main urban area of Lingang. Specific measures include systematic analysis of the main population, enhancing the multidimensional sensory experience and sustainability of the planting landscape space, in order to enhance the quality of the pocket park landscape space in the Lingang main urban area, provide convenient and comfortable leisure space for residents, and enhance the image and ecological benefits of the urban area. To provide useful insights for the construction of pocket parks in the continuously developing Lingang main urban area.
