根据2009年5月的温度、盐度和溶解氧观测数据，应用“对应分析法”对水团的分布范围和特性进行了分析，并探讨了苏北沿岸流对浒苔(Enteromorpha prolifera)暴发及漂移过程的影响。结果表明，春季苏北沿岸流向东南流动过程中，可以将海水中悬浮的浒苔繁殖体向南输运至长江冲淡水与苏北沿岸流交汇处，此处的浒苔繁殖体在适宜的条件下生长繁殖。在夏季风的作用下，长江口北部的浒苔与苏北沿岸海域的浒苔，随表层海流向北漂移，在地球偏转力作用下，漂移路径不断向右偏转，并最终在山东半岛南部海域聚集堆积。苏北沿岸流在浒苔暴发初期将繁殖体输送到条件适宜的生长区，并对浒苔向北漂移起到了重要作用。长江冲淡水向北扩展范围的增大对于浒苔的生长和繁殖起到了促进作用。查明浒苔扩散路径及输运机制不仅具有重要环境意义，而且对深入了解沿岸和河口区泥沙及污染物的扩散和输运机制具有指示作用。

Based on the temperature, salinity and dissolved oxygen data collected in the survey in May 2009, the distribution and features of the water masses were analyzed with the Comparison Analysis Method. Meanwhile, the role that Subei coastal current played in Enteromorpha prolifera outbreak and drift was discussed. During the southeastward flow in spring, Subei coastal current could carry the suspended Enteromorpha propagules to the meeting area of the Changjiang diluted water with Subei coastal current, where the propagules could grow and reproduce under suitable conditions. Affected by the summer monsoon, the E. prolifera in the north of the Changjiang Estuary and E. prolifera in Subei coastal area drifted northward with the surface currents. However, under the influence of Coriolis force, the drift path continuously deflected to the right and the E. prolifera gathered in the southern coast of the Shandong Peninsula at last. Subei coastal current transported the Enteromorpha propagules to the area under suitable conditions, and it played an important role in the northward drift of E. prolifera. The northward expansion of the Changjiang diluted water could promote the growth and reproduction of E. prolifera. The ascertainment of the diffusion path and transport mechanism of E. prolifera has an important environmental significance, and also helps us understand the sediments and pollutants diffusion as well as the transport mechanisms in coasts and estuaries.
