| 摘 要： | 2010年9~10月,对逊别拉河自然保护区浮游植物群落结构进行了初步研究,并利用生物指数对逊别拉河自然保护区水质进行评价。结果表明,浮游植物共计8门50种,以硅藻为主,28种,占56.0%;绿藻次之,15种,占30.0%;蓝藻2种,占8.5%;隐藻、裸藻、甲藻、金藻、黄藻各1种,共占14.0%;优势种类及常见种全部为硅藻门种类：尖针杆藻Synedra acus、脆杆藻Fragilaria sp.、扭曲小环藻Cyclotella comta、缢缩异极藻Gomphonemaconstrictum、舟形藻Acicular sp.、简单舟形藻Navicula simples、羽文藻Pinnularia sp.、桥弯藻Cymbella sp.、箱形桥弯藻Cymbella cistula。浮游植物平均数量为183.47×104ind..L-1,硅藻的数量较多,134.12×104ind..L-1,占61.82%;生物量为4.3740mg.L-1,硅藻的生物量最高3.9354mg.L-1,占89.9%。采用多样性指数H＇、J水质类型的评价标准对逊别拉河自然保护区水质进行评价,结果显示逊别拉河自然保护区H＇均值为3.01,J均值为0.88,水域属于寡污-清洁型河流,为鱼类提供了良好的水域环境。

| Abstract: | An investigation was conducted on the community structure of phytoplankton in the Xunbiela River Nature Reserve from September to October in 2010,and the water quality of the Xunbiela River Nature Reserve was assessed with biotic indices.The results showed that the phytoplankton assemblage was composed of 50 species in total,belonging to eight taxonomic groups.Bacillariophyta were represented by the highest number of taxa（28） followed by Chlorophyta（15）,Cyanophyta（2）.The percentage of Cryptophyta,Euglenophyta,Pyrrophyta,Chrysophyta and Xanthophyta was 14.0 %.Dominant species were Synedra acus,Fragilaria sp.,Cyclotella comta,Gomphonema constrictum,Acicular sp.,Navicula simples,Pinnularia sp.,Cymbella sp.,Cymbella cistula.The average cell density of phytoplankton was 183.47×104ind.·L-1 and the average biomass was 4.3740 mg·L-1.Cell density and biomass of Bacillariophyta were the highest,134.12×104ind.·L-1 and 3.9354mg·L-1 respectively.The percentage of Bacillariophyta cell density and biomass were 61.82% and 89.9 % respectively.The diversity of phytoplankton in that river was abundant.In addition,combining of H＇（3.01）、J（0.88）diversity indices,the water quality was between os-clean type in Xunbiela River Nature Reserve.It provided a suitable habitat for fishes. |
