海绵城市建设需要清晰可操作的控制指标作为指导,年径流总量控制率作为海绵城市建设的核心指标,需要在海绵城市总规层面进行细化和量化。以重庆市悦来新城的海绵城市建设为例,以水文、水动力模型为工具,将年径流总量控制指标量化到各类用地,并提出了各控制指标在建设中的应用。 Sponge city construction requires clear and operable control indicators as a guide, the annual runoff total control rate as a core indicator of sponge city construction, need to be in the sponge city general level refinement and quantification. Taking the sponge city construction of Yuelai New Town in Chongqing as an example, taking the hydrological and hydrodynamic model as a tool, the annual runoff total quantity control index is quantified to all kinds of land use, and the application of each control index in construction is put forward.
