摘　　要：长江流域河水中的氮、磷污染负荷主要来自面源。长江中下游地区分布有大量的圩垸,这些圩垸中的面源污染通过圩内地表径流聚集并出圩,久旱后如果突遇暴雨,极易产生冲击负荷,从而对圩外的受纳水体会产生较大的影响。选择长江流域具有典型代表性的圩垸作为研究对象,通过对2次暴雨过程的出圩面源污染负荷进行实时监测,获得了典型圩垸面源产生及排放的定量数据,进而对圩垸面源污染负荷出圩的时空分布规律进行了探讨。对长江流域典型圩垸的基本情况以及对典型圩垸面源污染负荷所制定的监测方案及其实施情况作了介绍。The nitrogen and phosphorus pollution loads in Yangtze River Basin is mainly from the non- point pollution. A large number of polder areas are distributed in the Yangtze River Basin,and the non- point pollution is concentrated in the polder through surface runoff and then flows out the polder,which would cause pulse load and affect the water quality of outside polders. Several representative polder areas are selected as research object and the data of non- point pollution generation and emission were obtained through the real time monitoring during 2 rainstorms. The temporal- spatial distribution laws of non- point pollution releasing from polder are discussed. The basic conditions of the polder in Yangtze River Basin,the non- point pollution monitoring scheme and its implementation are introduced.
