| 摘 要： | 于2001年1月～2003年1月对福建省漳江口红树林区水体浮游植物群落的季节变化进行了研究。结果表明,漳江口红树林区浮游植物以硅藻门种类为主,优势种为长菱形藻(Nitzschia longissima)和菱形藻(Nitzschia sp.1)等,同时出现多种裸藻、绿藻和甲藻。本次调查共鉴定到浮游植物31属87种(包括变种),其中硅藻门23属75种(包括变种),蓝藻门3属3种,绿藻门1属4种,金藻门1属1种,甲藻门2属2种,裸藻门1属2种。浮游植物密度变化范围为2.78×104～1.14×106个/L,平均为3.51×105个/L,季节变化为双峰型。出现大量的底栖硅藻和淡水性藻类是该水域浮游植物的一个特点。浮游植物的组成和结构表明该水域水质较好。

| Abstract: | Structure of phytoplankton communities in waters of mangrove natural reserve in the estuarine of the Zhangjiang River, Fujian Province, China was studied seasonally from Jan. 2001 to Jan. 2003. Water samples were collected every three months and observed under a light microscope. The results showed that dominant species were diatoms in each season, such as Nitzschia longissima and Nitzschia sp.1. Some taxa belonging to Euglenophyta, Pyrrophyta and Chlorophyta also occurred in the water. Totally 87 taxa(including variety) in 31 genera were identified, in which 75 taxa in 23 genera belonged to Bacillariophyta, and 3 taxa in 3 genera for Cyanophyta, 4 taxa in 1 genus for Chlorophyta, 1 taxon in 1 genus for Chrysophyta, 2 taxa in 2 genera for Pyrrophyta, 2 taxa in 1 genus for Euglenophyta, respectively. Cell density of phytoplankton ranged from 2.78×104 to 1.14×106 cells/L, and average density was 3.51×105 cells/L. The communities were characterized by abundant estuarine species and benthic diatom related with erosion by tide and wind wave, which distributed in the inter-tide in the mangroves. Nanodiatoms are an important component in phytoplankton. Water quality in mangrove area in the estuarine of the Zhangjiang River was in good condition according to composition and structure of phytoplankton communities. |
