By simulating river plume evolution under the combined action of tide and estival wind field averaged over many years , we have found that the modeled salinity distribution is consistent with the observed one rather well , which means the river plume development plays an important role in adjusting the salinity distribution in the surface layer of bohai sea 通过检验河流羽流在潮汐和渤海夏季多年平均风场共同作用下的发展特征，发现计算得到的表层海水盐度分布与实测值相当吻合，因此可以认为河流羽流发展对于渤海夏季盐度分布起着重要作用。
