摘要：

在分析不同低影响开发技术(Low Impact Development, LID)措施的径流削减效果的基础上, 提出了基于LID径流削减效率的LID指数的模型, 进而设计了LID设施选择图, 以根据建成区径流污染削减目标而快速选择适宜的LID设施类型及不同LID设施类型的比例. 结果表明, 随着LID指数增加, 雨水径流量及雨水径流污染物呈类似指数形式降低, 且LID指数越大, LID径流削减率越大, 但是径流削减的边际效应逐渐降低; 该模型灵活性较高, 具有探索应用意义.

Abstract:

In this paper, we propose the concept of “LID (low impact development) Index” and “LID Runoff Reduction Efficiency” based on an analysis of runoff cutting efficiency for different LID technical measures. A map was designed to help quickly select the appropriate LID facility and its proportions according to the pollution reduction target in a built-up area. It shows that when the‘LID index’ increases, surface runoff and pollutants exhibit a similar exponential function form; the larger the LID index, the lower the “LID runoff reduction efficiency”. The model data is easy to obtain and flexible, rendering potential applications worthy of exploration.
