低影响开发单项设施模拟模型研究与应用进展

随着我国城市化进程的加快,城市内涝、雨水径流污染及水质恶化等问题日益严峻。低影响开发(LID)作为目前国际上城市水环境保护和可持续发展的雨洪管理新策略,在削减城市雨洪和滞留污染物等方面效果显著。为更好的模拟LID措施对环境带来的影响,不同尺度低影响开发模拟模型应运而生。本文总结了SWC、HYDRUS、DRAINMOD、RECARGA等典型小尺度单项设施模拟模型的特点、结构、适用条件和优缺点,分析了现有典型单项设施模拟模型的不足之处,指出模型参数选择、模型适应性检验以及水质水量耦合模型研发为今后的研究方向。

Advance in simulation model research and application for single facility of low impact development

With the acceleration of urbanization process in China, the problems involving urban waterlogging, rainwater runoff pollution and water quality deterioration have become increasingly serious. As a new stormwater management strategy of international urban water environmental protection and sustainable development, the low impact development (LID) strategy can dramatically reduce urban stormwater and detained pollutants. In order to better simulate the effects of LID on the environment, different scale LID simulation models have been developed. This paper summarizes the characteristics, structures, application conditions, advantages and disadvantages of typical small scale simulation models for single facilities of LID, including models of SWC, HYDRUS, DRAINMOD, and RECARGA.The shortcomings of existing typical single facility model are analyzed. The research trends in the future are put forward, which include the parameter selection, the adaptability verification of model and the coupling model development of water quality and quantity.
