低影响开发的7种城市雨洪管理模型

Seven Stormwater Management Models in Low Impact Development

现代城市降雨径流量增大、峰值增加和径流面源污染等问题日益严峻,国外以"尊重自然、结合自然"为核心理念的低影响开发(Low Impact Development,LID)雨洪管理模式已取得一定成效。以国外应用于LI D的7种城市雨洪管理模型为研究对象,概述其模拟原理、方法和适用范围。通过比较分析,表明:7种雨洪管理模型都适用于LID设施单因素评估模拟,但没有一种模型可以全面模拟LID设施。

With many serious problems coming, such as increasing rainfidl runoff, higher peak and non-point source pollution problems, the stormwater management of Low-impact development （LID） of which the core concept is ＂Respect for nature, Combined with nature＂ stormwater management has made certain achievements. The review compares seven existing stormwater management models which are applied to LID in foreign countries concerning their principles, t＇unctions and applications. And then, it comes to conclusion that these seven models are suitable for unilateral evaluation of LID. However, there is no model that can simulate LID comprehensively.
