| 摘要: |
| 自从1980年6月中美关于长江口及其邻近陆架海区的沉积动力学联合考察开始以来，关于长江径流人海后路径的时空变化问题，引起了中外学者的广泛兴趣。
在这次中美联合考察之前，作者曾根据1980年以前的实测水文资料和余流资料，分析了洪水期本区的盐度分布和海流结构。本文目的是根据中美联合考察所得到的资料和历史资料，对长江冲淡水实测路径的性状作进一步的分析，并拟对影响长江冲淡水复杂多变路径的若干动力学问题作一初步分析。 |

| Abstract: |
| The“trimodal distribution'' of the Changjiang Diluted Water (CDW) in June, 1980 is analyzed and some dynamical aspects of its path are discussed in this paper. The main results are as follows:(1) The “ trimodal distribution”of the CDW may be caused by the interaction of large discharge of Changjiang River, strong tidal currents and mean alongshelf currents (the “ East China Sea Coastal Current ” and the “ Tai wan Warm Current”) within the estuary and over the adjacent shelf and the complex inner shelf topography. (2) The large discharge, the rapid cross-shelf increase in depth and the relic river valley in studied area have a direct influence on the behaviour of the path of the CDW (3) A simple estimation shows that the mean alongshelf current，general1y speaking，may have a limited influence on the path of the CDW. |
