摘　　要：2006年6月-8月对天津港南部海区浮游植物的群落组成进行了初步研究,结果表明,浮游植物群落主要由硅藻、甲藻组成,也有少数的蓝藻,其生态类型主要为温带近岸型。根据各站浮游植物所获样品的生物密度,分别对样品的多样性指数、均匀度、丰度和优势度等进行统计学计算,该区Shannon-Wiener多样性指数平均为2.91,表明该海域总体为轻度污染海域。Community composition of the phytoplankton in the southern sea of Tianjin habor was preliminary studied during June and August in 2006. The result showed that community composition of the phytoplankton was composed of Diatoms, Pyrrophyta, and few green Algae. The ecotype belonged to temperate and neritic species. According to the density of phytoplankton each station, the diversity index, uniformity, abundant and dominance of the phytoplankton each station had been calculated. The diversity index of Shannon - Wiener in the area was average 2.91. The results showed that the sea was under light pollution.
