| 摘 要： | 目的]掌握新疆某水库浮游植物群落变化特征。方法]2016年对新疆某水库10个采样站位的浮游植物及水体主要理化因子进行了3次调查。结果]共鉴定出浮游植物56种(属),其中优势种(属)10种。种类组成上,由春季的金藻-硅藻型转变成夏季硅藻-绿藻型再到秋季蓝藻-硅藻型。浮游植物总平均生物量为7.32 mg/L,生物量季节变动显著,春季高于夏季,秋季最低。垂直分布方面,春季和夏季浮游植物生物量表层均高于中层和底层,秋季各水层间差异不显著。PCA分析显示库区浮游植物群落结构从春季到秋季的显著梯度变化情况,入库水流与库区浮游植物群落结构差异显著。结论]研究结果为水环境评价与保护、资源合理利用和生态系统可持续发展提供了参考。

| Abstract: | Objective] The aim was to study community characteristics of pbytoplankton in a reservoir of Xinjiang.Method] We carried out three investigations on phytoplankton and physical and chemical factors of 10 sites in a reservoir of Xinjiang in 2016.Result] It was identified 56 species,10 species out of which once formed dominant populations.The specific composition shifted from chrysophyta and bacillariophyta to bacillariophyta and chlorophyta,to further establish cyanophyta and bacillariophyta.The total mean biomass of phytoplankton was 7.32 mg/L.The biomass changed significantly,and the peak biomass of spring was higher than summer with the lowest in autumn.The biomass of surface was higher than middle layer and bottom layer in spring and summer,and the differences between each layer did not represent obviously.PCA showed significant gradients changes of phytoplankton community from spring to autumn in the area of reservoir and notable differences of phytoplankton community between inflow and reservoir.Conclusion] The results provide reference for water environment evaluation and protection,reasonable utilization of resources ecosystem sustainable development. |
