大通湖浮游植物群落结构及其与环境因子关系
Phytoplankton' s community structure and its relationships with environmental factors in an aquaculture lake, Datong Lake of China
摘要
Abstract
From December 2008 to October 2009, a seasonal investigation was conducted on the phytoplankton' s community structure and its relationships with environmental factors in Datong Lake. With the comparison of the historical data in 1960, the potential effects of intensive aquaculture on the aquatic environment were analyzed, aimed to provide theoretical support for the sustainable fishery of freshwater lakes. A total of 98 phytoplankton species belonging to 7 phyla and 54 genera were collected, among which, Peridinium bipes, Chroomonas acuta, Chlorella vulgaris, Cry-tomonas ovate, Cyclotella meneghiniana, Crytomonas erosa, Anabaena circinalis, Microcystis aerugi-nosa, and Anabaena azotica were the dominant species, and had obvious seasonal variations. The mean annual cell density of the phytoplankton was 1. 84×106 cells · L-1, being the highest in summer (16.4×l06 cells · L-1) and ranged from 1.71×l06 to 1.98×l06 cells · L-1 in the other three seasons. The values of the abundance index, Shannon index, and Pielou index of the phytoplankton community were 2. 01-4. 55 , 1.26-2.69, and 0. 69-1. 27, respectively. Canonical correlation analysis (CCA) showed that water depth, water temperature, transparency, and water total phosphorus content, oxidation-reduction potential, and electrical conductivity were the main environmental factors affecting the phytoplankton community structure in the Lake.关键词
