摘要
雨水花园作为低影响开发的主要措施之一,在径流水量和水质控制方面具有显著效果,被广泛应用于海绵城市建设。文章就雨水花园的研究进展、关键问题进行阐述,针对雨水花园中硝态氮去除不稳定的问题提出3个研究方向:在雨水花园介质中引入缺氧区,种植对硝态氮利用效率高的特定植物,寻找吸附硝态氮的新型介质。
Rain garden is one of the main measures of low impact development, which has a significant effect on runoff and water quality control. It is widely used in the construction of sponge city. In this paper, the research progress and the key issues of rain garden were expounded. Three research fields regarding unstable removal of Nitrate nitrogen in rain gardens were put forward, which were introducing anoxic region into the medium of rain garden, planting plants with high utilization efficiency of nitrate-nitrogen and seeking for new materials to adsorb nitrate-nitrogen.
