摘　　要：2001年7月至8月,在新疆维吾尔自治区17个采样地采集硅藻标本,经光镜观察,共鉴定出羽纹藻属(硅藻门)的中国新记录5种2变种,即:喜盐羽纹藻Pinnularia halophilaKrammer、模糊型羽纹藻P.obscuriformisKram-mer、奥瑞恩达羽纹藻P.oriundaKrammer、瑞卡德羽纹藻P.reichardtiiKrammer、近曲缝羽纹藻P.substreptorapheKrammer、近曲缝羽纹藻博恩变种P.substreptoraphevar.bornholmianaKrammer和淡绿型羽纹藻小变种P.viridiformisvar.minorKrammer,并对其分类学特征以及生境特征进行了描述。为新疆的藻类资源提供了基础资料,为中国淡水羽纹藻科志书的编写积累了资料。Xinjiang Uygur Autonomous Region covers an area of one sixth of Chinese territory,largest in area among all the province-level administrative regions of China. Xinjiang is situated in the hinterland of Eurasian continent and is under the control of a typical extratropical belt continental climate. Special geographic position and peculiar climate characteristic make algae resources very abundance in this region, but the research of algae flora is relatively weak. Diatom materials were collected from Xinjiang during the period of July to August,2001. Materials were obtained from a wide variety of habitats in the investigated area. In the field, samples were preserved with 4% formalin and kept in the Herbarium of the Biology Department of Shanghai Normal University. Microscope slides were prepared by acid digestion method and mounted in Canada balsam or Hyrax gum. Light microscope observations were conducted using a Nikon E800 DIC microscope at magnification × 1000 and a Nikon digital cameral DXM1200. In the observation, five species and two varieties of Pinnularia （Bacillariophyta） are new records of China,They are Pinnularia halophila Krammer, P. obscuriformis Krammer, P. oriunda Krammer, P. reichardtii Krammer, P. substreptoraphe Krammer,P. s var. bornholmiana Krammer and P. viridiformis var. minor Krammer. The taxonomic characters and habitats of them were described. The study will provide basic data for algae resource investigation of China.
