| 摘 要： | 2006年7月至2007年10月对山东近岸的威海湾、荣成湾、桑沟湾、靖海湾、五垒岛湾及乳山湾(37°28.7'-36°46.3'N,121°28.8'-122°39.6'E)的26个站位按季节进行了4个航次的现场调查,分析了6个海湾不同季节的微型藻类及营养盐情况,并进一步对几种主要微藻类群与各种营养盐之间的相关性进行了研究.结果表明,各海湾微型浮游植物的平均丰度在456.3×104-2332.2×104cell/L之间;夏季和春季的主要优势种为硅藻:冬季主要优势种为黄藻;秋季主要优势种为隐藻.不同微藻类群与不同营养盐的相关性差异显著,其中,与NH4-N的相关性依次为:绿藻＞黄藻＞隐藻＞甲藻＞硅藻＞金藻,相关系数依次分别为0.965、0.929、0.761、0.748、0.671和-0.304;与NO3-N的相关系数的绝对值为金藻＞隐藻＞甲藻＞硅藻＞黄藻＞绿藻;与PO4-P的相关系数的绝对值则为甲藻＞金藻＞绿藻＞黄藻＞隐藻＞硅藻.

| Abstract: | The data of survey in six local bays obtained in July and December 2006, and April and October 2007, in northeast Shandong Peninsula show that the average abundance of phytoplankton varied from 456.3×104 to 2332.2×104 cell/L. The dominant species in spring and summer was Bacillariophyta, in autumn was Cryptomonas, and in winter was Xanthophyta. Average abundance and vertical distribution of them was analyzed. Besides, average abundance of nanophytoplankton and major nutrients in summer were also studied. Statistically, the coefficients between main nano-phytoplankton and different nutrients were determined. The results show that the coef?cients of NH4-N were Chlorophyceae (0.965), Xanthophyceae (0.929), Cryptophyta (0.761), Pyrrophyta (0.748), Bacillariophyta (0.671), Chrysophyta (-0.304); those of NO3-N was in order of Chrysophyta > Cryptophyta > Bacillariophyta > Pyrrophyta > Xanthophyceae > Chlorophyceae; and those of PO4-P was Chrysophyta > Pyrrophyta > Chlorophyceae > Xanthophyceae > Cryptophyta > Bacillariophyta. |
