SWMM辅助海绵城市专项规划的指标分解方法研究

《指南》提出了试算法与模型模拟法对海绵城市专项规划中的年径流总量控制率这一刚性指标进行分解落实,但由于《指南》尚处于试行阶段未对如何运用模型模拟法进行指标分解作出解答,且以SWMM为典型代表的水文水力模拟研究也较少以此作为切入点展开探讨。因此,研究借助SWMM模型探索出一条具有普遍适用性的指标分解途径,通过现状评估、刚性指标分解及引导性指标分解三个阶段完成年径流总量管控指标的分解,并借助案例对分解赋值方法进行详尽阐述,愿能为今后海绵城市专项规划的编制工作提供些许参考。

Research on Index Decomposition Method of SWMM Assisted Sponge City Special Planning

The Guide proposes using Test Algorithm and Model Simulation Method to decompose the rigid index,Annual Total Runoff Control Rate in Sponge City Special Planning,However,because the Guide is still in the trial stage when there is no answer for how to use the Model Simulation Method in index decomposition,and there are less Hydrological and Hydraulic Simulation Researches with SWMM as a typical representative.This method is used as a starting point for study.Therefore,this research in virtue of SWMM model explores a universally suitable index decomposition approach,through three stages as present situation assessment,the rigid index decomposition and instructive index decomposition to complete the decomposition of Annual Total Runoff Control Index,and cases are used to present elaboration on case assignment method,hopefully providing some reference for the compiling work of Sponge City Special Planning in the future.
