铜陵市河流冬季浮游植物群落结构及其与环境因子的关系
Phytoplankton' s community structure and its relationships with environmental factors in the rivers of Tongling City, Anhui Province of East China in winter
摘要
Abstract
Tongling is one of the main non-ferrous metal mining areas in China, and the biodiversity in the river ecosystem of this area is seriously affected by heavy metals as a result of mining activi-ties. In the winter in 2010, an investigation was conducted on the community structure of phyto-plankton and its relationships with environmental factors in the main sections of the rivers in Tongling. A total of 203 phytoplankton species were identified, belonging to 96 genera and 8 phyla. The community structure of the phytoplankton differed obviously in different river sections, but the communities were all dominated by Bacillariophyta, Chlorophyta and Cyanophyta. The phytoplank-ton abundance ranged from 9.1×10 to 6.5×107 cells·L-1, and the quantity of the phytoplankton in the river sections directly carried with mining waste water was significantly low. The Shannon in-dex of the phytoplankton community at different sampling sites ranged from 0 to 3.45, with a signif-icant discrepancy in different river sections. There existed significant correlations between the densi-ty and group number of phytoplankton and the CODCr and cadmium, copper and zinc concentrations in the rivers, and the concentrations of river total nitrogen, NH4+-N, NO3--N, and copper, CODCr and pH were the main environmental variables affecting the phytoplankton' s community structure and its spatial distribution. Although the nutritional status of the river waters had greater effects on the community structure of phytoplankton, the effects of the heavy metals there from mining enter-prises could not be neglected.关键词
