摘    要:本文在总结前人成果的基础上,进一步分析了长江冲淡水输运和扩散的途径。文章指出,长江冲淡水输运和扩散的途径有两种:顺岸南下型在冬、夏季都存在,它主要以杭州湾的次级锋面流和沿岸锋密度流为代表;转向型从5~6月开始,台湾暖流低密水和东海高密水之间的密度锋是长江冲淡水向外海扩散的通道

关 键 词:河口环流  长江冲淡水  东海高密水环流  杭州湾流型  密度锋

Abstract:The paper further analyzes the path of transportation and diffusion of Changjiang diluted water on the basis of summarizing the achievements obtained by predecessors. It is indicated that the paths of transportation and diffusion of Changjiang diluted water can be separated into two types. One, known as coastal southward type, exists in winter and summer. It is a frontal flow which consists mainly of coastal front flow and sub front flow of Hangzhou bay. Another one, known as turning type, starts from May to June every year. The density front between the low density water of Taiwan warm current and the East China Sea dense water is the channel of the Changjiang diluted water diffusing to offshore.
Keywords:esutary circulation  Changjiang diluted water  East China Sea dense water circulation  Hangzhou bay flow pattern  density front
