【摘要】 选择北京城区某楼房小区作为20世纪90年代以来新建成小区的代表,在其原有排水系统的基础上进行改造,纳入雨洪利用系统单元,通过对研究区内降雨量,屋顶、道路等系统的产流量进行实际观测,运用统计分析、回归分析等方法对观测数据进行整理,从雨洪利用的角度出发对不同下垫面降雨产流规律进行研究,并分析了因雨洪利用措施而导致的下垫面变化对降雨产流规律的影响。研究结果对城区建设的规划设计工作,以及城区综合雨洪利用的研究工作都具有着十分必要的现实意义。更多还原

【Abstract】 Taking a residence community in Beijing as a typical newly-built residence community since the 1990s,its drainage system is modified with the rain-flood utilization system,and then an actual observation is made on the rainfall and the runoffs from roofs and roads etc.therein.The observed data are compiled.Based on this,the law of the runoff yield under various underlying surfaces is studied from the viewpoint of the rain-flood utilization,in which the effect from the variation of the underlying surface on the runoff yield due to the adoption of the measures of rain-flood utilization is analyzed as well.The study result has a practical significance for the study on the comprehensive utilization of rain-flood within an urban area.更多还原
