基于GI措施的城市雨水管理模型评析

摘要

In consideration of the application universality of models and the upgrading possibility of softwares , we make a review on eight urban stormwater management models based on green infrastructure ( GI) measures.These models have been applied widely in recent years .Firstly , the eight models are classified in terms of the rain and n runoff water quality control , GI economic benefit analysis , integrated model of GI stormwater management and eco-nomic analysis , respectively .Secondly , the eight models are described in detail with regard to five major criteria in-cluding representative GI measures , spatial scales , algorithms used for modeling , data inputs and outputs , and user interface and handling of the tool .Thirdly, the eight models are compared in terms of the number of GI measures they can represent , modeling approaches , data requirements , modeling accuracy , and regional limitations .Fourth-ly, the application of several models in China are analyzed , and the problems urgent to be solved are also pointed out.Finally, in view of the advantages and disadvantages of the current models , we proposed the direction and trend of the development of urban stormwater management models in future .This study is designed to help urban stormwater managers and researchers to understand the fundamental knowledge of different GI stormwater manage -ment models , and help them to select appropriate model in practice according to their needs .%鉴于模型应用的广泛性以及软件升级的可能性，评析了国内外近些年较为流行的8个基于绿色基础设施（ GI）的城市雨水管理模型。分别从GI雨水水质和径流量控制、GI经济效益分析、GI雨水管理及经济分析集成模型3方面对模型进行分类；从GI实践的典型性、空间尺度、模型的算法、数据的输入和输出、用户界面和工具应用几个方面对模型进行详细阐释；从模型支持的GI类型、模拟方法、输入参数、模拟精度、应用范围几个方面比较了模型的不同属性；总结了几个典型模型在中国的应用情况，指出亟待解决的问题。针对目前模型的优缺点，提出未来雨水管理模型研发的方向和趋势。通过本研究，帮助城市雨水管理者和研究人员了解不同的基于GI措施的雨水管理模型的特征及用途，有助于他们在实践中根据自身需求恰当选用模型。
