| 摘 要： | 2011年9~10月,对逊别拉河底栖动物进行了调查研究,并利用生物指数对水质进行评价。结果表明,共采集到15目28科55种底栖动物,其中水生昆虫种类最多为37种,分属7目16科,占总数的67.27%。出现频率排在前三位的分别是粗腹摇蚊(Pentaneura sp.)、狭萝卜螺(Radix lagotis)和半球多脉扁螺(Polypylis hemisphaerula)。底栖动物平均密度为64.80ind.m-2、生物量为4.43g.m-2。功能摄食类群以捕食者占优势,共计为23种,刮食者15种,收集者11种,撕食者6种。BI生物指数评价结果表明,逊别拉河水质比较清洁。 |

| Abstract: | An investigation was conducted on the community structure of macrobenthos in the Xunbiela River from September to October in 2011,and the water quality was assessed with biotic indices.A total of 55 species of macrobenthos were collected,belonging to 15 orders and 28 families,with 37 species of aquatic insects(67.27% of the total) belonging to 16 families and 7 orders.Pentaneura sp.,Radix lagotis and Polypylis hemisphaerula) were of the first three species in incidence order.The macrobenthos were found at an average density of 64.80 ind·m-2 and at a biomass of 4.43 g·m-2.The predators including 23 species were predominately found in all functional feeding groups,the others including 15 shredders,11 collectors and 6 scrapers.The BI assessment revealed that the water quality in Xunbiela River was clearer. |
