巢湖藻类组成与环境因子典范对应分析
Canonical Correspondence Analysis of Algae Community and Its Environmental Factors in the Lake Chaohu, China
摘要
Abstract
This research was performed during May 2008 and May 2009 at the Lake Chaohu, aiming to investigate the seasonal variations of algal species and water quality. A total of 48 kinds of algal species belonging to 6 phyla and 31 genera were identified, among which, the species in Chlorophyta accounted for about 47.9％ of the total species. The dominant specie was the Microcystic aeruginosa, the frequency of which was 90.9％. No significant difference was found on algal species across three sampling sites. Overall, Margalef values varied from 0.10 to 1.84, while algal density varying from 12.65 to 825.00×106 cell L-1, beth showing lower values during winter season. The Chl-a concentrations varied from 1.30 to 41.10 μg· L-1 and TP concentrations varied from 0.06 to 0.48 mg· L-1, both having a significant higher values in autumn and summer. CCA analysis showed that the spatial distribution of algae was greatly affected by the aquatic environmental factors and TP could be the major one.关键词
