城市雨洪管理低影响开发技术研究与利用进展

Advances in low impact development technology for urban stormwater management

低影响开发(LID)作为一种新兴雨水管理技术,在消减城市雨洪和滞留污染物等方面效果显著.本文系统介绍了LID技术体系,综述了国外关于3类典型LID设施(生物滞留池、绿色屋顶和透水路面)对暴雨径流和主要污染物的消减效果研究,以及LID技术在模型模拟、成本效益分析和管理体系等方面的研究成果和经验;并在此基础上分析了目前LID技术存在的问题和研究的不足;最后从LID技术的研究方向、合理设计和科学管理等方面提出建议.旨在通过国外研究的成果和经验为LID技术在国内的标准制定和广泛实践提供科学依据和建议.

Low impact development （LID）, as an innovative technology for stormwater manage- ment, is effective to mitigate urban flooding and to detain pollutants. This paper systemically intro- duced the LID technology system, and summarized the reduction effects of three typical LID facili- ties （ i.e., bio-retention, green roof and permeable pavement） on stormwater runoff and main pollu- tants in recent literature, as well as research outcomes and experiences of LID technology on model simulation, cost-benefit analysis and management system. On this basis, we analyzed the problems and limitations of current LID technology studies. Finally, some suggestions about future research directions, appropriate design and scientific management were put forth. This work intended to pro- vide scientific basis and suggestions for widespread use and standard setting of LID technology in China by referencing overseas studies.
