摘　　要：针对昆山市圩内低田(半高田)封闭灌区和圩外高田开放灌区,尝试利用全市境内发达的河湖水系以及数量众多的沟渠塘堰,构建两种典型水循环生态运转模式,通过灌溉站的水动力驱动,持续削减区域内农业和养殖业尾水中的N、P等污染物,并将净化处理后的尾水作为灌区用水和养殖补水,完成对水资源和营养物质的循环利用,为实现区域内农业面源污染"零排放"提供可能。Kunshan have been working on construction and promotion of ecological irrigation district for years.This paper attempts to use the good lake water system and channel pond in Kunshan,aimed at closed irrigation system of diked areas and open irrigation system building two types of water cycle operating mode,continuous cutting down N,P pollution via water power drive, then use purification tail water as irrigation water and farming feed -drinking,to achieve recycling of water resources and nutrients,make it possible of regional“Zero-emission”of agricultural non-point source pollution.
