摘要
为了更好地利用和推广低影响开发(LID)技术,通过文献法,综述了生物滞留系统、屋顶绿化、透水铺装、下凹式绿地等几种常用LID雨水管理方面的国内外研究进展。文献研究表明,在径流量控制方面,4种LID的效果都较为理想;在营养物去除方面,生物滞留池、透水铺装和下凹式绿地效果明显,屋顶绿化对氮、磷等营养物去除效果较差,且存在径流中氮、磷增加的风险;在重金属去除方面,生物滞留池、透水铺装效果较好,下凹式绿地对重金属的去除效果一般,屋顶绿化的材料可能会成为径流中重金属的来源。未来应在以下几个方面加强研究:不同LID的水质和水量控制机理,LID性能评价的优化,LID建模技术的改进和完善,流域规模的LID试验,不同植物对径流污染物的生物利用度等。
In order to better utilize and promote low impact development(LID)technology,through the literature reviewing,this study has summarized the domestic and international research progress of several commonly used LIDs,such as bioretention system,green roof,permeable pavement,and concave green space.Literature research shows that:in the aspect of runoff control,the effects of four LIDs are ideal;In the aspect of nutrient removal,the effects of bioretention pool,permeable pavement and concave green space are obvious.The effect of green roof on nitrogen and phosphorus removal is poor,and there is a risk of increased nitrogen and phosphorus in runoff;In the aspect of heavy metal removal,the bioretention pool and the permeable pavement are better,but the concave green space is general,and the material of green roof may become the source of heavy metals in the runoff.It is recommended to strengthen research in the following aspects in the future:water quality and water volume control mechanisms for different LIDs,the optimization of LIDs performance evaluation,the improvement and perfect of LIDs modeling technology,watershed size LIDs test,the bioavailability of different plants to runoff pollutants.
