摘　　要：为了解钱塘江河口突发污染物的输移规律,采用垂向平均的平面二维潮流水质模型,模拟了突发溶解性污染物在输移过程中的时空变化,研究了在不同径流量、潮汐、江道地形、事发地点、源强等情况下的污染物输移规律,得到了突发事故对取水口水质的影响程度,包括影响持续时间,最大浓度等,其成果可为决策部门制定应急对策、编制应急预案等提供技术支撑。In order to understand the transporting law of burst pollutants in Qiantang River estuary,using vertical average plane two-dimensional tidal current water quality model of Qiantang River estuary,this paper simulated the spatial and temporal variation of burst dissolved pollutants in the transport process. It studied pollutants＇ transport rule in different conditions of runoff,tide,river channel topography,incident site,pollution intensity,etc.,obtained the degree of sudden accident＇ s influence on the water quality of water intake,including the impact duration,maximum concentration,etc.The results can provide technical support for decision-making department to develop contingency measures,prepare contingency plans,etc.
