摘要:
根据年径流总量控制率的应用方式，分析了采用“1-雨量径流系数”作为年径流总量控制率的不合理性。从雨量径流系数和年径流总量控制率的定义出发，推导得出了雨量径流系数和年径流总量控制率两者的内在关系。提出径流污染控制指标宜采用年径流总量控制率，径流总量控制指标宜采用雨量径流系数，并指出对于重庆地区这种天然雨量径流系数较高的山地城市，径流污染控制是年径流总量控制率取值的决定性因素。
Abstract:
According to the application mode of the volume capture ratio of annual rainfall, the irrationality of using “1-volumetric runoff coefficient” as volume capture ratio of annual rainfall is analyzed. Based on the definition of volume capture ratio of annual rainfall and volumetric runoff coefficient, the internal relationship between volumetric runoff coefficient and volume capture ratio of annual rainfall is derived. It is suggested that the runoff pollution control indicator should adopt volume capture ratio of annual rainfall, and the runoff total volume control should adopt the volumetric runoff coefficient. The result showed that for the mountainous city with large natural volumetric runoff coefficient just like Chongqing, runoff pollution control is the decisive factor for the value of the volume capture ratio of annual rainfall.
