As an essential part of the urban ecosystem, optimizing the layout of urban parks is of great significance in improving the quality of the urban environment and the residents’ quality of life in the context of urban renewal. Taking Lixia District of Jinan City as the research object, we collect and organize POI data and urban park data and analyze the layout characteristics, service capacity evaluation, and demand analysis of urban parks with the help of ArcGIS. The results show that the distribution of urban parks in Lixia District is unreasonable, with significant spatial differences in density, tremendous pressure on park services, and the service capacity of urban parks in some lots needs to meet the crowd’s needs. Based on this, a strategy for optimizing the layout of urban parks in Lixia District is proposed from three aspects: site selection of new urban parks, construction of urban park system, and improvement of internal quality of existing urban parks. The research results can provide a scientific basis and reference for the planning of the urban park system in the urban renewal process, which is of great significance for improving the quality of the urban environment and residents’ quality of life.
