摘要
1982~1983年、2008~2010年两时段对虎门口邻近水域浮游植物种类组成、群落结构与数量分布进行调查,结果表明:1982~1983年检出浮游植物7门9纲20目42科100属,平均细胞密度24 500cells/L,生物量0.1176mg/L;2008~2010年检出7门10纲21目45科83属,平均细胞密度65 550/L,生物量0.1486mg/L。浮游植物可分为3个群落:河口半咸水性群落、淡水性群落和近岸广温低盐性群落。两时段的目、科、属群落相似性指数分别为0.93、0.92和0.78,优势属为0.55。2008~2010年耐污、富营养化指标性藻类大量出现,一些水域可见超富营养和污染指示属。比较该水域浮游植物的种类组成、数量的历史变化,分析变动原因。
Based on the surveys of the population composition, community structure and distribution of the phytoplankton conducted from 1982 to 1983, there were 100 genera phytoplankton under 7 phyla, 9 classes, 20 orders and 42 families in the Humen estuary and its adjacent waters, with the mean abundance of cells 24500 ind/L and biomass 0. 1176 mg/L. According to the secondary investigation from year 2008~2010, there were 83 genera phytoplankton from 7 phyla, 10 classes, 21 orders and 45 fami- lies in these waters, with the mean abundance of cells 65550 ind/L and biomass 0. 1486 mg/L. There were 3 communities as estuarine brackish-water community, freshwater community and nearshore community with eurythermic and hypohaline species. Similarity index of orders, families, genera in two periods was 0.93, 0.92 and 0.78, respectively, the dominant species is 0.55. We found there were a lot of eutrophied and polluted phytoplankton species and the typical biologic population in 2008 ~ 2010. The composition and distribution of all kinds of the phytoplankton were compared and analyzed as well.
