本文根据四十和五十年代的历史资料、黑潮调查资料、福建海岸带调查资料及渔场调查等实测资料,对台湾海峡及其邻近海区的水文要素,按四分之一度的经、纬度区域作多年月平均,进行了1～12月的0～200米水层(0、10、50、100、200米)的温度、盐度、密度、水色透明度等水文要素的水平和垂直分布的整理。绘制水平分布图112幅,垂直剖面图20幅。通过水文状况的空间分布和时间变化的分析,本海区主要受黑潮水、南海水和闽浙粤沿岸水等不同水系的消长和冬、夏交互作用季风的影响,构成了本海区水文状况的基本特点。同时展现了上述水系随月份而生、消的过程,对台湾海峡海区来说,春、冬、秋季受黑潮水的影响较大,受南海水影响较弱;春末和夏季则主要是受南海水和粤东沿岸永的影响,并有一少部分是黑潮水的影响;闽浙沿岸水的流势冬季大于夏季,最后进行了初步讨论。
Based on the historical data of the 40s and 50s, the survey data of the Kuroshio Current, the survey data of the coastal zone of Fujian Province and the survey of fishing grounds, this paper analyzes the hydrological elements of the Taiwan Strait and its adjacent sea areas by quarter-degree latitude and longitude The area was averaged for many years. The horizontal and vertical distributions of hydrological factors such as temperature, salinity, density and water color transparency of 0 ~ 200 m water layer (0, 10, 50, 100 and 200 m) from January to December sort out. Draw horizontal distribution 112, vertical section 20. Through the spatial distribution of hydrological conditions and the analysis of time variation, the influence of the growth of the Kuroshio, the South China Sea, the coastal waters of Fujian, Zhejiang, Guangdong and Guangdong waters and the monsoon of winter and summer interact with the monsoon, which is the basic hydrological condition in this area Features. At the same time, it shows the process of the above-mentioned water system’s birth and elimination with the month. For the Taiwan Strait sea area, the spring, winter and autumn are greatly influenced by the Kuroshio, and are less affected by the South China Sea water. In the late spring and early summer, Water and the coast of eastern Guangdong Province, and a small part of them are influenced by the Kuroshio. The flow of water along the coasts of Fujian and Zhejiang is greater in winter than in summer, and a preliminary discussion is made at the end.
