摘　　要：新疆阿尔泰山两河源自然保护区是新疆北部地区湿地分布最集中的地区之一,2015年7月在该地区采集藻类植物标本共50号,在对标本鉴定过程中,发现新疆鼓藻类植物新记录有11个分类单位,隶属于5个属,包括7种4变种,分别为:线纹新月藻近平截变种[Closterium striolatum var.subtruncatum(West&West)Krieger]、埃伦宽带鼓藻[Pleurotaenium ehrenbergii(Brébisson)De Bary]、长圆凹顶鼓藻[Euastrum oblongum(Greville)Ralfs]、瘤状凹顶鼓藻(Euastrum verrucosum Ehrenberg ex Ralfs)、乳突微星鼓藻(Micrasterias papillifera Brébisson ex Ralfs)、托马森微星鼓藻(Micrasterias thomasiana Archer)、双眼鼓藻张开变种(Cosmarium bioculatum var.hians West&West)、斑纹鼓藻宽变种[Cosmarium conspersum var.latum(Brébisson)West&West]、项圈鼓藻(Cosmarium moniliforme Ralfs)、雷尼鼓藻(Cosmarium regnellii Wille)和雷尼鼓藻膨大变种[Cosmarium regnellii var.dilatatum(Messikommer)Krieger&Gerloff]。并对其11种新记录植物的形态学特征进行了详细的描述。50samples were collected in July 2015 from the Altay Two River-Source Nature Reserve wetland in Xinjiang,China.Through identity,11 taxa from desmids were newly recorded in Xinjiang which belonged to 5genera.They were Closterium striolatum var.subtruncatum（West West）Krieger,Pleurotaenium ehrenbergii（Brébisson）De Bary,Euastrum oblongum（Greville）Ralfs,Euastrum verrucosum Ehrenberg ex Ralfs,Micrasterias papillifera Brébisson ex Ralfs,Micrasterias thomasiana Archer,Cosmarium bioculatum var.hians West West,Cosmarium conspersum var.latum（Brébisson）West West,Cosmarium moniliforme Ralfs,Cosmarium regnellii Wille and Cosmarium regnellii var.dilatatum（Messikommer）Krieg-er Gerloff.These new records would enrich study data of desmids in Xinjiang.
