摘要
本文指出根管藻(Rhizosolenia)对黄东海邻接水域水系的指标意义。1987年调查期内共采到根管藻15种,3变种和2变型,占我国海域已报导的总种数的80％;在调查海域内出现了3个由不同种数和不同优势种组成的、具有不同生态性质的根管藻群落;这些群落的分布位置及其生态性质与现场海域不同水文性质水系的分布密切相关。
The significance of the Genus Rhizosolenia as an indicator in the early summer in 1987 was reported in this paper.15 species, 3 varieties and 2 formae of the Genus Rhizosolenia were sampled during the investigation, which were 80% of the total number of this Genus reported in our country. Three communities, different in total number of cells, dominant species and ecological characteristics, appeared in the investigated area. Their distributions and ecological characteristics were closely related to the distribution of the water mass of different hydrological features.
