摘    要:198 4~ 2 0 0 0年间 ,对娘子关泉域的藻类植物进行了 15次采集 ,共采得藻类植物标本 2 0 0余号。经鉴定 ,有10 7种 ,隶属 7门 ,32科 ,4 9属。其中 ,以绿藻门的种类最多 ,有 13科 ,19属 ,4 5种。其次是裸藻门 ,有 2科 ,7属 ,2 6种。排在最后的是轮藻门 ,有 1科 ,1属 ,3种。群落主要包括 8类 ,即刚毛藻 红毛菜群落 (Cladophora Bangiacom munity) ,刚毛藻群落 (Cladophoracommunity) ,拖拉藻 轮藻群落 (Chara Thoreacommunity) ,弯枝藻 拖拉藻群落(Composopogon Thoreacommunity) ,水绵 双星藻群落 (Spirogyra Zygnemacommunity) ,无隔藻群落 (Vaucheriacommunity) ,串珠藻群落 (Batrachospermumcommunity)和泡状饶氏藻群落 (Jaoacommunity)。其中 ,有的群落类型已趋于消失或消失 ,许多种类已成为濒危物种 ,其原因主要是人为因素造成藻类植物生存环境的改变或破坏。本文也提出了相应的保护对策

Stream algae in Niangziguan,Shanxi:a preliminary study
Abstract:Niangziguan, located in Pingding County, Shanxi, has a large cool spring with rich algae resources. The flora and feature of stream algae in Niangziguan has not been previously reported except for the occurrence of some species. We sampled the algae fifteen times from 1984 to 2000. In the research, 107 species of algae have been found, comprising 7 divisions, 32 families and 49 genera. Chlorophyta was represented by the most species, with 45 species from 13 families and 19 genera. Euglenophyta was ranked as second, with 26 species, in 2 families and 7 genera. Charophyta had the least species, with only 3 species, which belonged to 1 family and 1 genus. The algal flora of Niangziguan was mainly divided into 8 kinds of communities: Cladophora Bangia community, Cladophora community, Chara Thorea community, Composopogon Thorea community, Spirogyra Zygnema community, Vaucheria community, Batrachospermum community, and Jaoa community. In this article, changes in number of algal species and communities are also reviewed. The results show that the species diversity of algae has been decreasing markedly and many species have become endangered. This was mainly caused by human activities, which damaged the habitats of algae. The research provides some important reference data for exploring and utilizing algal resources in Niangziguan.
Keywords:stream algae  flora  community  Niangziguan
