摘　　要：在流星分析和ｔ－Ｓ点聚分析的基础上，在台湾东北部ＩＳ断面和东海中部ＰＮ断面上选取适当的纵剖面作为分界面，将以面分成东、西两侧，计算了界面两侧的海水交换星。结果表明：１．东海陆架区海水交换可归纳为两种类型，即“穿插型”和“进退型”。２．参与分界面处海水交换总量的年平均是夏季最大，春、秋季次之，冬季最小。黑潮水向陆架区输运量为０．５８×１０６ｍ３／ｓ，陆架水向黑潮刚输运量为０．８４×１０６ｍ３／ｓ；参与交换的总量为１．４２×１０６ｍ３／ｓ．３．相对输运量计算结果表明；黑潮水对陆架区水文状况的影响是冬季最强，秋、春季次之，夏季最弱，而陆架水对黑潮区水文状况的影响是夏季最大，秋季次之，春季和冬季最小。Based on volume transport and T-S diagram analysis, an appropriate profile was selected as interface on section IS northeast of Taiwan and on section PN in the middle of the East China Sea (ECS), and the odious were divided into an east and a west side, then the quantitier of sea water exchange between both Sides of the interface were calculated. The results show:1. Water exchange of the continental shelf and in the ECS can be divided into two types:the 'crossing type' and the 'forward and back type'.2. The annual mean value of sea water exchange taking part in the interface is the largest in summer, second in spring and autumn, and smallest in winter. The transport of the Kuroshio Water (KW) to the Shelf area is 0. 58×106m3/s, the transport of the Shelf Water(SW) to the Kuroshio area is 0. 84×106m3/s, the total amount of transport taking part in the exchange is 1. 42×106m3/s.3. The calculation of relative transport shows that the KW influence on the hydrosraphic conditions of the shelf area is the strongest in summer, second in autumn and spring and the weakest in summer, but the SW influence on the hydrographic conditions of the Kuroshio area is the largest in summer, smaller in autumn and the smallest in spring and winter.
