摘要
基于低影响开发的城市雨水排放系统能够降低城市化过程中不断增加的径流污染和洪涝灾害的影响,近几年在发达国家日益受到重视并得到广泛的工程应用。选择几个有关低影响开发雨水管理模型进行介绍,并分别从模型的应用范围、时空分辨率、污染物的种类、用户界面等方面进行了比较分析。现有模型在模型的简化、参数的局限性、模型的兼容性、污染物去除过程描述的准确性等方面还存在一定局限性,在今后城市雨水管理模型发展过程中应将更多的低影响开发措施结合到模型中,不断完善模拟方法和提高模型的集成和实用能力。
Urban stormwater drainage system based on low-impact development （LID） can reduce the effects of runoff pollution, flood and waterlogging disasters, which are continuously increased during urbanization. In recent years, the system has increasingly attracted more and more attention and gained wide engineering applications in developed countries. Several stormwater management models for LID are introduced and compared from aspects of application scope, temporal and spatial resolution, kinds of contaminants, user interface and so on. There are some limitations for the existing models in simplification, parameters, compatibility, description accuracy during removal of contaminants and so on. More measures for LID will be taken during development of urban stormwater management models to perfect simulation methods and improve integration and utility capability of the models.
