摘　　要：2011年6月对黑龙江兴凯湖湿地自然保护区进行了藻类标本采集,在对硅藻进行分类研究的过程中,观察到羽纹藻属(硅藻门)中国新记录植物6个分类单位,包括5种1变种,分别为埃氏羽纹藻Pinnularia aestuarii Cleve、中心羽纹藻Pinnularia cruxarea Krammer、纤弱羽纹藻钝形变种Pinnularia distinguenda var.obtusa Krammer、球状羽纹藻Pinnularia gibbiformis Krammer、特殊羽纹藻Pinnularia notabilis Krammer、鲜明羽纹藻Pinnularia perspicua Krammer。对这些种类的分类学特征进行了详细的描述,与同属中相似种类进行了比较,为黑龙江兴凯湖湿地藻类资源调查提供了基础资料。The genus Pinnularia Ehrenberg is one of the largest diatom genera in the world. Pinnularia is closely related to Caloneis Cleve （1891）, suggesting that they should be considered as the same genus. Now, the two genera are listed as two single genus in the taxonomy system of Hustedt. During the investigation of diatoms from Xingkai Lake, we observed 45 taxa in Pinnularia that preferred to live at pH 6 to 7. Six of 45 taxa were reported as newly recorded species in China that includes Pinnularia aestuarii Cleve, Pinnularia cruxarea Krammer, Pinnularia distinguenda var. obtuse Krammer, Pinnularia gibbiformis Krammer, Pinnularia notabilis Krammer, and Pinnularia perspicua Krammer. The morphological characteristics and the morphological differences with other similar species were described in detail. This investigation provides the basic information of algae in Xingkai Lake.
