摘　　要：调查了大面积实施稻鸭共生技术地区的稻田表面水和周围流域河水以及水生生物相。结果表明:稻鸭共生田的表面水的EC、COD、T-N等值与传统栽培田水质相比普遍增高,稻鸭共生期间稻田排水易导致水质污染,为了防止周边水质的污染,需要彻底做好水的管理工作。The experiment was conducted to investigate the effects of rice-duck integrated farming on the water environment,water biodiversity in paddy field and surrounding river.The results was showed,the EC,COD,T-N value ect.of the surface water in paddy field were all increased,except pH value.The water quality was bad if we drain away paddy field water during rice-duck integrated farming.So we need have good rules for supervision water in case of bad water quality.
