摘　　要：以我国北方某城市30年的实测降雨数据为依托,采用《海绵城市建设技术指南——低影响开发雨水系统构建(试行)》中年径流总量控制率的说明方法,进行实操计算,并总结计算过程及方法。通过计算方法的研究以及近两年海绵城市试点建设的实践经验,对年径流总量控制率这一指标的应用进行探讨,并指出年径流污染控制的效果目标,年径流总量的控制是实现这一效果目标的有效途径和方法之一。Based on 30 years of rainfall data from a city in North China,the calculation method of the capture ratio according to the description from the Guide was further applied and summarized. Through the study of the calculation method and the applications of the sponge city pilot projects in the latest two years, the application range of the volume capture ratio of total annual rainfall was discussed. Meantime, it＇s indicated that the annual rainfall pollution control should be the key control target, and the control of the annual rainfall volume should be the effectively control way to achieve this key target.
