EFFECT ASSESSMENT OF SPONGE CITY CONSTRUCTION IN THE INTERNATIONAL ECO-BUSINESS DISTRICT IN SONGJIANG DISTRICT IN SHANGHAI BASED ON SWMM
-
摘要: 海绵城市建设旨在恢复城市自然调蓄能力，提升生态环境和城市韧性。以上海市松江国际生态商务区为研究区域建立SWMM模型，评估海绵城市建设对区域降雨径流控制和污染负荷控制效果，结果表明：较之传统开发模式，海绵城市建设能够显著滞蓄雨水、降低区域径流总量、削减入河污染负荷，有效减轻区域排涝压力和水环境压力。对于3，5，20，50 a重现期的2 h降雨，海绵城市径流总量分别削减40.8%、39.5%、37.0%、35.8%；对于5 a重现期的2 h降雨，TSS、COD、TN、TP的削减率分别为36.3%、39.4%、32.9%、47.6%。Abstract: The construction of the sponge city is aimed to restore the natural storage capacity of the city and improve the ecological environment and urban resilience. In this paper, the SWMM of international eco-business district in Songjiang district in Shanghai was established to evaluate the effect of sponge city construction on regional runoff control and pollution load control. The results showed that: compared with the traditional development mode, the construction of sponge city could significantly store rainfall, then reduce regional runoff, also reduce the pollution load into the river, and effectively reduce the pressure of regional drainage and water environment. The total runoff of sponge city was reduced by 40.8%, 39.5%, 37.0% and 35.8%, respectively, after 2 hours rainfall with recurrence period of 3-year, 5-year, 20-year and 50-year. The reduction of TSS, COD, TN and TP was 36.3%, 39.4%, 32.9% and 47.6%, respectively, after 2 hours rainfall with 5-year recurrence period.
