摘要
用聚类分析法划分浅海水团能够克服大洋水团分析法进行分析所遇到的一些困难,它在根据不同海区特点确定临界值与检验值时有较大的灵活性。本文讨论了浅海变性水团与中心渔场的关系。结果表明,东海底层冷水、东海表层水和大陆沿岸水对渔业生产有重要影响。因此作者认为可以用聚类分析法来研究分析。
The cluster analysis method to determine the water-masses in the shallow waterarea can overcome some difficulties which are met in using analysis method of theoceanic water-masses. According to the features of different sea area, this method ap-plied in defining the marginal value and inspectoral value possesses great flexibility.The correlations of the modified water--masses in the shallow water area with thecentral fishing grounds are discussed in this paper.The results show that the bottom layer cold waters and surface layer waters ofDong Hai Sea and the coastal waters of continent are important factors effecting thefishery production in this area. Therefore. it is necessary to use this method in re-search and analysis of the variation.
