为了实现屋面雨水利用系统量化评估中径流系数的精确取值，通过连续3年（2010-2012年）对河北省邯郸市不同屋面类型（屋面坡度和材料）及降雨特征（降雨深度和强度）的屋面径流进行实地监测，得到了各场实际降雨屋面径流系数的不同取值．研究结果表明，屋面径流系数的取值分布与各降雨事件的降雨深度相关性较强，其他影响因素对其影响较小．场次径流系数的取值与降雨深度呈显著的分段线性关系．根据1960-2008年的日降雨数据资料，计算得出邯郸市年均屋面径流系数可近似按照0．62这一常数进行取值．该研究成果可用于屋面雨水利用系统的量化评估及运行分析．

In order to accurately estimate the runoff coefficient for the quantity assessment of the roof rainwater harvesting system RRHS great differences in the value of event runoff coefficient ψERC were observed by field monitoring under different roof types roof slope and material and diverse rainfall distributions rainfall depth and intensity in three years 2010 to 2012 in Handan Hebei China.The results indicate that the distribution of ψERC is more highly correlated with the event rainfall depth than other factors. The relationship between ψERC and the rainfall depth can be well represented by the piecewise linear function.Further based on the daily rainfall data over the period from 1960 to 2008 the value of the annual runoff coefficient ψARC is calculated. Although the total rainfall depth in each year is different ψARC in Handan can be considered as a constant 0.62 approximately. The results can be used for the quantity assessment and performance analysis of the RRHS.
