摘要随着经济的快速发展,城市水资源的供需矛盾日益突出,雨水作为一种洁净、新型、储量丰富的资源越来越得到人们的重视和使用。详尽而系统地阐述了雨水资源的多元化应用,结果表明:屋面雨水经过初期弃流收集以后可以作为城市的杂水使用;绿地雨水主要通过设置下凹式绿地和设置径流小沟、渗水管和集水井等使雨水就地入渗补给地下水;非机动车道和人行道的雨水主要通过透水面进行充分下渗回归地下水;城市多余雨水也可以用于农业灌溉。通过研究可以使雨水利用更加系统化和多样化,为不同区域的城市雨水利用提供依据。

AbstractWith the rapid development of economy, the contradiction between supply and demand of urban water resources is increasingly prominent. Rainwater as a kind of clean, new and abundant resource was more and more get people's attention and application. This paper expounds the diversity of rainwater resources detailedly. The results showed that roof runoff after early abandon flow can be used as the miscellaneous water; green space water can be used to local infiltration recharge and supply the groundwater by setting the recessed groove, the runoff water penetration tube and the collecting well; water in non-motor vehicle lanes and sidewalks mainly collected through the surface to fully back infiltration of groundwater; city rainwater surplus can also be used for agricultural irrigation. This study can be used to study the rainwater more systematic and diversified and provide the basis for rainwater utilization of different parts of urban.

随着中国城市化进程的加快,水资源的供需矛盾越来越突出,城市生活用水、工业用水和生态用水不断增加,使得农业用水不断被侵夺,地下水的压力也越来越大。如何开源节流,使得原本紧缺的水资源能够得到更加合理的应用越来越引起人们的关注。而雨水作为一种资源丰富、收集容易和处理简单的水资源越来越受到人们的关注,目前,很多学者在这方面也做了大量的研究。现在国际上关于雨水利用的研究主要有这么几个方面,即屋面雨水收集利用[1]、绿地雨水蓄渗利用和地面雨水收集利用[2-3]。其中屋面雨水因为水质好、容易收集越来越得到人们的青睐。也有部分学者在研究住宅小区和高校这些特殊区域的雨水利用[4-5]以及雨水的其他利用[6-8]。……
