摘要
应用模糊聚类方法,采集东海30个站表层及底层1996-1998年夏季的水温(T)、盐度(S)、溶解氧(DO)、磷(P)、三态氮(N)、硅(Si)、pH值等九个指标的测样数据,对东海水团进行划分,其表层水团配置为大陆沿岸冲淡水(I),黄东海混合水团(Ⅱ),台湾暖流水(Ⅲ),黑潮表层水(Ⅳ)等水团。底层水团配置为黑潮次表层水团(V),黄海冷水团(Ⅵ),台湾暖流水(Ⅲ)等水团。并分析了1996-1998年夏季由大陆径流和外海水团势力强弱影响所致的东海水团变动特征及沿岸冲淡水转向问题,同时讨论了东海水团分布与鲐■渔场关系。
According to the data collected from 30 sections with parameters such as Temperature (T), Salinity (5), Dissolved oxygen(DO) , PO4-P, SiO3-Si, NO2-N, NO3-N, NH4-N and pH in the East China Sea in the summers of 1996,1997 and 1998 with fuzzy clustering method, this paper shows distribution of water masses in surface and bottom layers. The water masses included Coastal Water Mass ( I ), Huanghai-Donghai Mixing Water Mass (II), Taiwan Warm Water Mass (III), Kuroshio Surface Water Mass (IV), etc. in the surface layer and Kuroshio Subsurface Water Mass (V), Yellow Sea Cold Water Mass (VI), Taiwan Warm Water Mass (Ill) in the bottom layer. The remarkable dynamic variation of water masses in the East China Sea in summer from 1996 to 1998 is described. The main reason of the dynamic variation on water masses with surface layer and the trend about the Coastal Hushing Water Mass is analyzed. Moreover the relation between the distribution of water masses and Mackerel Scad fishery is discussed.
