摘　　要：对整个长江口研究区域洪季盐水入侵过程进行模拟.验证结果与实测资料基本一致,较好地模拟出地形变化对水流结构的影响,盐度的分布与实测资料所反映的情况相吻合,盐度纵向扩散梯度从外海向上游递减,北支盐度始终高于南支,再现了长江口地区水流特征和盐水入侵的基本规律.The saltwater intrusion process at the periods of flood season was simulated in study area of Yangtze River. The salinity distribution of the area generally agreed with measured data. The gradient of salinity horizontal diffusion decreases upstream from the sea, and the salinity of north branch is always higher than that of south branch. The basic law of the saltwater intrusion in the Yangtze estuary was reproduced.
