Abstract:

于2010年7月至2011年6月期间,对太湖贡湖湾及梅梁湾微囊藻的种类组成及其群落的时空分布差异进行调查,并探讨影响微囊藻群落时空分布的环境因子.结果表明,7-11月太湖贡湖湾和梅梁湾都表现为鱼害微囊藻(Microcystisichthyoblabe)、惠氏微囊藻(M.wesenbergii)及铜绿微囊藻(M.aeruginosa)顺次成为优势种的演替过程,其余时间段内以鱼害微囊藻及其它微囊藻为主.通过CCA分析环境因子与微囊藻属内各种类之间的关系,发现温度是驱动其季节演替的主要因素.两个湖湾之间及同一个湖湾内中心与岸边区域的微囊藻种属分布差异不明显.但是受到风的作用,两个湖湾中下风向位置的微囊藻细胞丰度较高.惠氏微囊藻和铜绿微囊藻更易受到风的影响而向下风向位置迁移,这是因为惠氏微囊藻和铜绿微囊藻群体粒径相对较大,易于漂浮在表层而通过表层迁移聚集于下风向处.可见风引起的表层迁移是影响微囊藻群落空间分布的重要因素.
