摘　　要：城市绿地是海绵城市建设的主要载体之一,相较于城市绿地中的城市广场用地、城市附属绿地、城市防护绿地,城市公园绿地具有较高的雨洪管控潜力,但因现行的城市公园绿地海绵改造建设过程中缺少对选址和时序的考量,造成其雨洪管控能力未能有效发挥。为充分发挥城市公园绿地的雨洪管控能力,研究基于德尔菲法和层次分析法构建了城市公园绿地海绵适宜性评价体系,得出城市公园绿地海绵适宜性评价结果,提出区域层面城市公园绿地优化策略。通过SWMM(Storm Water Management Model)模型进行情境模拟,对比不同情境数据发现:相较于城市公园绿地现状系统模拟结果,适宜海绵建设区域优化后总径流量削减约5.12%,高峰径流量削减约19.605%;较适宜海绵建设区域优化后总径流量削减约19.02%,高峰径流量削减约23.645%。模拟数据表明区域层面的海绵优化策略可以有效提高城市公园绿地雨洪管控能力。基于区域层面的海绵优化策略,提出场地层面的城市公园绿地海绵优化引导建设策略。城市公园绿地海绵适宜性评价与优化流程有望指导未来不同类型城市绿地海绵的优化建设。Urban green space is one of the main carriers of sponge city construction. Compared with urban square land, urban subsidiary green space, and urban protective green space in urban green space, urban park green space has a higher potential for storm and flood control. However, due to the current urban green space, the lack of consideration of site selection and time sequence construction for sponge construction during the transformation and construction of the sponges in parks and green spaces has resulted in the failure of effective use of the rain and flood management and control capabilities of urban parks and green spaces. In order to give full play to the rain and flood management and control capabilities of urban parks and green spaces, the study constructed an urban park green space sponge suitability evaluation system based on the Delphi method and analytic hierarchy process. The results of urban park green space sponge suitability evaluation results were proposed and the regional level urban park green space optimization was proposed strategy. The SWMM(storm water management model) model is used to conduct scenario simulation and compare different scenario data. It is found that compared with the current system simulation results of urban parks and green spaces, the total runoff volume after optimization of the suitable sponge construction area is reduced by about 5.12%, and the peak runoff volume is reduced about 19.605%;After the optimization of the more suitable sponge construction area, the total runoff is reduced by about 19.02%, and the peak runoff is reduced by about 23.645%. The simulation data shows that the sponge optimization strategy at the regional level can effectively improve the rain and flood management and control capabilities of urban parks and green spaces. Based on the sponge optimization strategy at the regional level, this paper proposes a site-level urban park green space sponge optimization guide construction strategy. The suitability evaluation and optimization process of urban p
