摘要:
采用显微照相技术，对2016年7月采自新疆喀纳斯国家级自然保护区，包括河流、湖泊、沼泽和溪流等地的50份藻类标本进行分类学研究。结果显示：有5个鼓藻类植物为中国新记录，隶属于3属，包括2种3变种——圆形鼓藻（Cosmarium cyclicum Lundell）、近丘凸鼓藻大形变种（Cosmarium subochthodes var.majus Schmidle）、瘤状凹顶鼓藻高山变种［Euastrum verrucosum var. alpinum（HuberPestalozzi）Krieger］、美国微星鼓藻［Micrasterias americana (Ehrenberg) Ralfs］和美国微星鼓藻博尔蒂变种（Micrasterias americana var.boldtii Gütwinski）。并对5个新记录鼓藻类植物的分类学特征和采集地生境进行了详细的描述。为新疆鼓藻类植物研究提供基础资料。
Abstract:
Through photomicrographic technique，the 50 samples collected from the Kanas Nature Reserve Xinjiang in July 2016 were identificated. The results showed that there were five taxa of desmids as new records in China，which belonged to 3 genera. They were Cosmarium cyclicum Lundell，Cosmarium subochthodes var.majus Schmidle，Euastrum verrucosum var. alpinum （HuberPestalozzi） Krieger， Micrasterias americana (Ehrenberg) Ralfs，and Micrasterias americana var.boldtii Gütwinski. In addition，the species identification character and circumstances were described in detail. These new records would enrich the study data of desmids in Xinjiang.
