摘　　要：《上海市城镇雨水排水规划(2020-2035年)》要求主城区(含中心城区)的排水系统设计重现期达到5年一遇。为此,以上海市中心城区某排水系统为研究对象,结合该排水系统内的海绵城市建设要求,定量化分析了源头绿色海绵设施和灰色调蓄设施对雨水排水系统提标的效果。结果显示,灰色调蓄设施可有效提高系统的排水能力,而相同调蓄容积的源头绿色海绵设施的提标效果较差,并与其服务面积比有关。进一步分析发现,可通过源头绿色海绵设施对径流系数的影响,定量化计算其对排水系统提标调蓄容积的贡献。The Shanghai Urban Rainwater Drainage Plan(2020-2035)requires that the design return period of the drainage system in the main urban areas(including the central city)should be five years.Therefore,the effect of source green sponge facilities and grey storage facilities on the upgrading of rainwater drainage system in the downtown area of Shanghai was quantitatively analyzed based on the construction requirements of sponge city in the drainage system.The grey storage facilities effectively improved the drainage capacity of the system.By contrast,the source green sponge facilities with the same storage capacity demonstrated poor upgrading performance,and there was a certain relationship with their service area ratio.Further analysis showed that the contribution of green sponge facilities to the storage capacity of the drainage system could be quantified through investigating the influence of green sponge facilities on the runoff coefficient.
