摘要
城区降雨径流过程主要受降雨过程和下垫面变化的影响。开展城区降雨径流观测试验,对不同下垫面条件的降雨入渗—径流关系进行研究,引用分布式水文模型,对4种下垫面条件的降雨径流关系进行摸拟,取得了较好的模拟效果,提出了科学化生态化城市建设的建议。
The process of runoff in urban area is mainly influenced by rainfall process and underlying surfaces variation. Through runoff observation test in urban area, it is studied of the relationship between rainfall infiltration and runoff in different underlying surfaces, The relationship between rainfall and runoff is simulated in 4 kinds of underlying surfaces by distributed hydraulic model, A good simulation is achieved and suggestions to contribute scientific and ecological city are given.
