Discussion on LID index model construction framework and its graphical application

Abstract

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.

Key words: LID, runoff pollution, sponge city
