| 摘要: |
| 随着经济社会的快速发展,目前我国正处在城镇化快速发展的时期,由此引发的城市水问题愈发突出,相关研究需求也愈加迫切.本文初步分析了城市化对降水和极端暴雨、流域产汇流规律及洪水、需水、供水及水资源保障、水质水环境及水生态系统等方面的影响.在分析城市水文效应的基础上,从学科发展和应用的角度,提出了当前城市水文学需要重点研究的问题,如城市极端暴雨的成因分析、城市暴雨洪水计算方法、城市雨洪资源化应用方法和关键技术等. |

| Abstract: |
| With the rapid economic and social development,China is now in a period of rapid development of urbanization,which is confronted with a lot of acute problems for us to carefully study.Some impacts caused by urbanization such as precipitation and extreme storm,runoff generation and flow concentration in river basin,flood,demand and water supply and water resources protection,water quality and water environment,and water ecosystem are analyzed in this study.Based on the analysis of urban hydrologic effects,key problems on which the urban hydrology research is focusing are presented,such as the cause analysis of urban extreme storm,the calculation method for urban storm with flood,and the methods and key technology applied to rainwater and flood resources utilization,from the point of view of subject development and application. |
