纬向垂直环流在东海渔场形成过程中的作用

本文收集并整理了1972年到1979年东海水产研究所及海洋局东海分局在东海区进行的水文调查资料，以及上海市海洋渔业公司同期的渔获资料，探讨东海纬向垂直环流在渔场形成过程中所起的作用，并讨论了利用该环流系统的有关资料进行渔情预报和渔场安排的可能性。

THE EFFECT OF TRANSVERSE VERTICAL CIRCULATION ON THE FORMATION OF FISHING GROUND IN DONG HAI

1. It has been proved by investigations since 1959 that there exists a transversevertical circulation system in the Dong Hai. 2. This circulation system consists of the surface rip current (the divergencecaused by wind in surface water), the subsurface current of the Kuroshio climbingup along the bottom towards the shore and the upwelling near the shore. The lattertwo are partly caused by meridional currents in the lower layers. 3. The subsurface water is short of dissolved oxygen, so it is able to drive fishshoal to the fishing ground. It plays an important role in the process of concentratingfishes. Besides that, the effects of upwelling and other suitable conditions make thewestern bound or the circulation system have the opportunity to form a fishing ground. 4. Based on the fundamental priciples of circulation, wo can apply the informa-tion of the circulation in a certain period to the fishing forecasts, in order to make thearrangement of fishing and the operation on the ground.
