| 摘 要： | 为了了解贵州高原水库蓝藻群落组成特征和微囊藻毒素分布,于2009年10月对贵州高原2座水库——万峰湖和百花湖采样调查。结果表明:万峰湖以蓝藻为主要优势藻,蓝藻中的拟柱孢藻(Cylindrospermopsis sp.)占绝对优势,浮游植物丰度在13.05×104～55.80×104 cells.L-1之间,蓝藻的丰度值占到了总量的82.55%,6个采样点中有3个(大坝、野鸭滩和革布)检出了微囊藻毒素MC-RR,且有1个点(革布)质量浓度超标,另外3个点(坝艾、坝达章和九里堡)未检出;百花湖以蓝藻、绿藻和硅藻共同构成优势藻,蓝藻中的假鱼腥藻(Pseudanabaena limnetica)是主要优势藻,浮游植物丰度在6.16×104～65.00×104 cells.L-1之间,蓝藻的丰度值在总体中所占比例为33.25%,3个采样点(大坝、岩脚寨和码头)均未检出微囊藻毒素。形成2个高原水库蓝藻群落结构和微囊藻毒素分布差异的原因可能是:2个水库中氮、磷营养盐水平不同引起浮游植物群落组成不同,进而导致了微囊藻毒素的分布出现差异。
