透水铺装径流调控效益研究进展

Runoff Management Performances of Permeable Pavements:a Review

透水铺装作为一种从源头控制雨水径流的低影响措施,具有降低地表径流量和洪峰流量、改善雨水径流水质、补给地下水等功能,因而,正被越来越广泛地应用于海绵城市建设。文章从透水铺装结构与分类、透水铺装径流调控机理、透水铺装水量削减与水质净化效益、透水铺装堵塞机理及影响因素等多个方面综述了国内外透水铺装径流调控研究进展,并从透水铺装流域/区域尺度径流调控效益、透水铺装维护方法、冬季透水铺装的径流调控效果、透水铺装污染物迁移转化规律和透水铺装全生命周期效益评价等方面提出了未来的研究趋势和重点,以期为透水铺装径流调控效益研究及透水铺装设计、建设和维护等提供理论和方法支持。

As one of the source control low impact development practices, permeable pavements can reduce surface runoff and peak discharge rate, improve water quality and recharge groundwater, therefore they are more and more widely used in the sponge city construction. This paper addresses the research of runoff management performances of permeable pavements around the world, with the aspect of the structure and classification of permeable pavements, the mechanism of runoff management of permeable pavements, the hydrologic performances and water quality influences of permeable pavements, the clogging mechanism of permeable pavement and its influence factors, as well as the monitoring and simulation methods of permeable pavements. Afterwards, there is a need for more future research on runoff management performances of permeable pavements, e.g., watershed/regional scale runoff management performances of permeable pavements, maintenance methods of permeable pavements, runoff management performances of permeable pavements in winter, transportation and transformation of pollutants in permeable pavements, and life-time assessment of permeable pavements. This review is expected to provide theoretical and technical supports for research, design, construction and maintenance of permeable pavements.
