| 摘 要： | 对洱海水质和浮游植物进行了调查, 分析了洱海藻类水华暴发季节水质营养水平及浮游植物多样性, 并探讨了洱海浮游植物种群演替的环境机制. 研究结果表明, 洱海蓝藻水华在6-10月份大量暴发, 蓝藻数量高达107 cells/L, 水华种类为微囊藻(Microcystis)属的一些种, 微囊藻在6-10月份占绝对优势, 最高可达90%以上. 分析5-11月洱海营养水平, 其中7月营养水平最高, 浮游植物生物量10月份最大(以叶绿素a表示). 使用SPSS里的pearson分析了浮游植物和各理化因子的关系, 结果表明相对于其他浮游植物种类, 总磷(TP)对微囊藻的影响比较大.

| Abstract: | Field studies were conducted in Lake Erhai from May to November in 2009. We investigated the phytoplankton composition and found that the cyanobacterial blooms occurred between June and October during which the phytoplankton abundance reached 107 cells/L or higher. The dominant species in the blooms were Microcystis sp., and their highest relative abundance could be above 90%. The analysis of the water quality showed that at currently Lake Erhai maintained a mesotrophic status. The trophic level of the water body was the highest in July, and the biomass of phytoplankton (Chl. a) reached the peak value in October. Furthermore, the results of the SPSS analysis suggested that compared to other phytoplankton species Microcystis sp. could be much more influenced by the total phosphorus (TP). |
