摘  要:对山西省辛安泉泉域大型藻类植物的分布特点进行了调查研究.研究结果表明:泉域内大型藻类植物种类丰富,共有55种,隶属于6个门,分别为蓝藻门、红藻门、黄藻门、硅藻门、绿藻门、轮藻门;群落类型多样,共有6大类型,分别为刚毛藻群落、轮藻群落、水绵-双星藻群落、等片藻-直链藻群落、无隔藻群落和串珠藻群落;藻体形态多样,有5种,分别为垫状、胶团状、胶质丝状体、丝状体和簇状;生长季节多样,种类数大致为春季>秋季>冬季>夏季;生境多样,共有4种固着基质,分别为石头、枯木、泥沙和其它藻体.相似性分析结果显示:辛安泉泉域的大型藻类与其它地区的相似指数都很低,一定程度上反映了地域性差异和生殖隔离现象.The distribution characteristics of macroalgae in Xin'an Spring was investigated.The results showed:(1) There were 55 species stream macroalgae,involved in 5 divisions,Cyanophyta,Rhodophyta,Xanthophyta,Bacillariophyta,Chlorophyta and Charophyta.(2) The macroalgal flora was mainly divided into 6 kinds of communities:Cladophora community,Chara community,Spirogyra-Zygnema community,Diatoma-Melosira community,Vaucheria community and Batrachospermum community.(3) There were 5 types of morphological forms,mats,gelatinous colonies,gelatinous filaments,free filaments and tufts.(4) There was different species number of stream macroalgae occurring in 4 seasons.It generally was springautumnwintersummer.(5) There were 4 types of attached substratums,stone,bedload,deadwood and other macroalgae.The Sorensen similarity indices matrice of stream macroalgae in Xin'an Spring and other districts were all very low.It indicated that the stream macroalgae in different locations had regional and reproductive isolation in some extent.
