| 本文是我国西沙群岛海产念珠藻目 Nostocales 蓝藻的第一部分。念珠藻目是一类具有异形胞而无真分枝构造的丝状蓝藻,它广泛分布在陆生环境中,但在海洋中的种类也很多。过去,有关我国海产念珠藻目的研究很少,仅有一些零星报道,迄今共记载了十二种。最近,作者将1975-1976年在我国西沙群岛采到的海产蓝藻标本进行了初步鉴定,表明念珠藻目在西沙群岛不仅种类多,而且有一定的数量。本文报道十七种,隶于三科八属,全部为西沙群岛地区新记录,其中除多变鱼腥藻 Anabaena variabilis Kuetzing，丝状眉藻 Calothrix confervicola (Roth) Agardh,粘滑眉藻 C. contarenii Bornet et Flahault,岩生眉藻 C. scopulorum (W.and M.) Agardh,扁平栅须藻 Isactis plana ( Harvey) Thuret和灰色微毛藻 Microchaete grisea Thuret等六种在我国沿海已有报道外,其余十种,即:胞内植生藻 Richelia intracellularis J. Schmidt,哈氏节球藻 Nodularia harveyana (Thwaites) Thuret,夏威夷节球藻N. hawaiiensis Tilden,附生双须藻 Dichothrix fucicola ( Kuetzing) Bornet et Flahault,刷状双须藻 D. penicillata Zanardini，博氏双须藻 D. Bornetiana Howe,多孢双歧藻 Scytonema polycystum Bornet et Flahault,铜锈微毛藻 Microchaete aeruginea Batters,维蒂微毛藻 M. vitiensis Askenasy 和细小微毛藻 M. tapahiensis Setchell 为我国海产蓝藻的新记录;中建双须藻 Dichothrix zhongjianensis sp.nov.为一新种。 |

| Abstract: |
| The present paper deals with descriptions of 17 species of the marine blue-green algae belonging to 3 families and 8 genera of Nostocales from the Xisha Islands. With the exception of6 species,i.e.,Anabaena variabilis Kuetzing, Calothrix confervicola (Roth) Agardh,C. contarenii Bornet et Flahault, C.scopulorum (W.and M ) Agardh, Isactis plana (Harvey) Thuret and Microchaete grisea Thuret reported from Guangdong and Shangdong Provinces,the other 10 species, i.e Richelia intracellularis J. Schmidt, Nodularia harveyana ( Thwaites ) Thuret, N. hawaiiensis Tilden, Dichothrix fucicola (Kuetzing) Bornet et Flahault, D.penicillata Zanardini, D.Bornetiana Howe, Scytonema polycystum Bornet et Flahault, Microchaete aeruginea Batters, M. vitiensis Askenasy and M. tapahiensis Setchell are new records for the Chinese marine blue green algal flora and 1 species-Dichothrix zhongjianensis sp. nov. is new to science. The specimens studied including the type specimen are deposited in the Herbarium of Institute of Oceanology, Academia Sinica at Qingdao. |
