| 摘 要： | 本文较详细地叙述了1960年以来黄,东海近海春季表、底层多年平均水温,增温率和水温的历年波动,以及海区的水系分布和变化的特点,并探讨了海区春季水温分布、变化与渔业的关系。 文章指出:黄海区多年平均水温四月中旬至五月初的表、底层均具有槽状分布特点。五月中旬表温变得相对均匀,底层在青岛东南外海形成具有相对独立性的冷水团。东海区的水温整个春季均具脊状分布特点。本文以距平小于-0.5℃,大于 0.5℃和居于±0.5℃之间作标准来划分冷年、暖年和正常年各种类型。 本文还结合渔业生产,分析了由海区水温水系各年的分布变化对鱼类洄游分布和渔期早迟的影响;指出掌握渔场水温的分布和变化对做好渔情预报的重要性,并提供作为指标的某些水温特征值。

| Abstract: | The present paper describes the many--years accumulated data of the growth rates;annual variations of surface and bottom water temperatures; the characteristics of watersystem distribution and the changes in inshore waters of Dong Hai and Huang Hai inSpring season since 1960. It has also disscussed the changes of the water tamperature in relation to the fisheries in these sea areas. There are specific the of the water temperature distribution in these sea areas inSpring season. In Huang IIai it is in the form of trough shape, the in Dong Hai it is inthe form of ridge shape. The water system of these sea areas is influenced very much bythe coastal cold water of Huang Hai, warm current of Taiwan, the fresh water currentfrom Chang Jiang and the cold water mass off the southeast coast of Qing Dao. The tem-perature changes and the variation of positions of them would greatly affect the tempera-ture statue and distribution of the whole sea area, and it seems one of the reasons that itleads the temperature distribution and variation of positions to be different each year. In combining with fishing operation, the variation and distribition of watertemperature is analysed in relation to the migration of fishes and the time of fishingseason. It is pointed out that investigation of water temperature distribution and changesin the fishing grounds is important in making fishery forecast. Some useful watertemperature indices are provided for fishery forecasting. |
