摘　　要：社区公园是与居民联系最为紧密的社区级公共绿色空间,实现其布局空间公平是推进基本公共服务均等化的重要需求。基于人工智能方法,从整体差异、区域间差异和分配差异选取评价指标,构筑数量、区位和面积的组合模式,量化分析三基础要素及其组合对社区公园布局空间公平的影响,经由姑苏区案例验证模拟结果。结果表明,社区公园布局由“少而大”转为“多而小”,3种要素在不同的空间公平层级产生影响:1)数量要素关联社区公园覆盖率以影响整体差异,整体差异共降低57.60%;2)区位要素改变居民与社区公园空间关系以影响区域间差异,区域间差异共降低59.41%;3)面积要素调整供需关系以影响分配差异,分配差异共降低44.32%;4)姑苏区社区公园布局的基础要素对空间公平的影响遵循上述模拟规律,但整体差异与分配差异变化更显著,而区域间差异变化则相对较小。揭示了社区公园布局基础要素对空间公平的影响规律,为落实社区公园布局空间公平理念提供支撑,为其规划优化提供精准化指引。Community parks are vital public green spaces at the community level that play a key role in urban environments,closely linked to residents'daily lives.These parks not only provide recreational and social benefits but also enhance the overall quality of life for residents.Achieving spatial equity in their layout,ensuring fair and equal access for all residents,is a critical objective to promote the equalization of basic public services.A well-distributed network of community parks allows people from all areas to enjoy green spaces,regardless of their residential location,which enhances the sense of inclusivity and cohesion within communities.In this study,we apply advanced artificial intelligence methods to simulate the supplyside layout of community parks.Our approach evaluates key indicators at three levels:1)the overall difference,which examines the equity of the layout throughout the entire area;2)the inter-regional difference,which focuses on spatial disparities among different regions;and 3)the distribution difference,which assesses the balance of park distribution within specific regions.These indicators are essential for understanding how community park layouts align with spatial equity goals.Using these metrics,we construct a variety of combination models that analyze the interplay of three basic elements:quantity,location,and area.Each model captures how different configurations affect spatial equity.Based on these models,we conduct a quantitative analysis to understand the impact of each factor-quantity,location,and area on spatial equity in community park layouts.By applying our models to realworld cases,particularly in Gusu District,we verify the accuracy of our simulations.Gusu District serves as a case study to test how well the simulation results align with actual patterns,enabling us to examine the applicability of our findings in real-life urban contexts.The findings demonstrate that the artificial intelligence simulation method allows for a highly effective,quantitative assessment of spatial eq
