摘　　要：在中国海绵城市建设不断推进的当下,优化海绵城市建设核心指标年径流总量控制率的制定策略对于平衡海绵城市建设的合理性与成本效益具有重要意义。采用传统工程策略叠加年径流总量控制率一阶变化率曲线进行经济性分析,并通过径流污染控制及排水管道设计目标进行验证,形成了一套年径流总量控制率“3+2”指标制定策略,即综合考虑年径流总量控制率分区图、年径流总量控制率与其一阶变化率曲线关系图、城市开发后自然水文条件接近开发前的原则,以及年径流总量控制率与排水管道设计目标的关系、与径流污染控制目标的关系;最后在宁波市海绵城市建设中付诸应用。结果表明:该策略提升了年径流总量控制率指标的合理性与经济性;根据该策略,宁波市年径流总量控制率制定为75%时,可实现工程合理前提下的海绵城市建设成本效益最大化。研究成果可为海绵城市建设提供参考。Currently,as sponge city construction continues to advance in China,optimizing the formulation strategy for the core indicator of annual runoff total control rate in sponge city development holds significant importance for balancing rationality and cost-effectiveness.By employing traditional engineering strategies superpositioned with the first-order change rate curve of the annual runoff total control rate for economic analysis,and validating it through runoff pollution control and drainage pipe design objectives,a"3+2"indicator formulation strategy for the annual runoff total control rate has been established.The proposed strategy comprehensively considers various factors,including the zoning map of the annual runoff total control rate,the relationship between the annual runoff total control rate and its first-order change rate curve,the principle of maintaining natural hydrological conditions post-urban development close to pre-development levels,as well as the connections between the annual runoff total control rate and drainage pipe design goals,and runoff pollution control objectives.Finally,this strategy was implemented in Ningbo's sponge city development.The research findings reveal that:①This strategy enhances both the rationality and economic efficiency of the annual runoff total control rate indicator.②According to this approach,by setting the annual runoff total control rate in Ningbo City at 75%,maximum cost-effectiveness in sponge city development can be achieved under reasonable engineering conditions.These research findings can serve as valuable references for sponge city development in other Chinese cities.
