摘　　要：我国城市化发展速度不断加快的同时,也带来了城市硬化面积占比增大的问题,在雨季易发洪涝灾害。海绵城市建设理念可有效提升城市排洪能力,同时可实现径流污染物的净化,现已逐渐得到推广。依托上海市城市道路设计方案,以横断面分幅形式和退让区域绿地情况作为控制指标,对4条道路设计方案进行分析,通过评价指标对道路设计成果进行评估,并基于海绵城市建设理念提出优化思路,研究成果可为现有城市道路优化设计提供参考。The continuous acceleration of the development of urbanization in China has also brought about the problem of an increase in the proportion of urban hardened areas,which is prone to floods during the rainy season.The concept of sponge city construction can effectively improve the flood discharge capacity of city,and at the same time achieve the purification of runoff pollutants,which has been gradually promoted.Based on the urban road design plan of Shanghai,four road design plans are analyzed with the cross-sectional format and the green space of the concession area as the control indicators.The road design results are evaluated through the evaluation indicators.And the optimization ideas are proposed according to the sponge city construction concept.The research results can provide the reference for the optimal design of the existing urban roads.
