摘    要:2010年8月对广东省6座水库及其入库河流的大型底栖无脊椎动物群落进行采样调查,并分别利用Goodnight-Whitley指数和BPI指数对水库及入库河流的水质进行评估。结果表明,水库共检出底栖动物13种,优势种为霍甫水丝蚓(Limnodrilushoffmeisteri)、苏氏尾鳃蚓(Branchiura sowerbyi)和八斑多足摇蚊(Polypedilum masudai),种类丰富度变动范围为2~5种,平均密度为277 ind/m2,变动范围160~480 ind/m2。入库河流的种类丰富度和密度均高于水库,共检出底栖动物28种,优势种为苏氏尾鳃蚓、霍甫水丝蚓、花翅前突摇蚊(Procladius choreus)和河蚬(Corbicula fluminea),种类丰富度变动范围为2~7种,底栖动物平均密度为382 ind/m2,变动范围192~816 ind/m2。水质评价结果表明,6座水库的水质状况总体良好,但入库河流均受到不同程度的污染,污染较为严重的黄岗河和黄羌河,其水库汤溪水库和公平水库也产生了污染。

关 键 词:水库  底栖动物  水质生物评价

Abstract:The macroinvertebrates community in six reservoirs and their inflow rivers were investigated in August 2010 in Guangdong Province.Goodnight-Whitley index and BPI index were used to evaluate the reservoir and inflow river water quality respectively.Results showed that a total of 13 taxa were collected in reservoirs.The dominant species were Limnodrilus hoffmeisteri,Branchiura sowerbyi and Polypedilum masudai.Taxa richness ranged from 2 to 5 and mean macroinvertebrate density was 277 ind/m2which ranged from 160 to 480 ind/m2.Both taxa richness and density were higher in inflow rivers than in reservoirs.A total of 28 taxa were collected in inflow rivers,and the community was dominated by Branchiura sowerbyi,Limnodrilus hoffmeisteri,Branchiura sowerbyi and Corbicula fluminea.Taxa richness in rivers ranged from 2 to 7 and mean macroinvertebrate density was 382 ind/m2which ranged from 192 to 816 ind/m2.Water quality assessment results showed that reservoirs showed good water quality as a whole while all the rivers were polluted.There were pollution in Tangxi and Gongping reservoir whose inflow rivers showed relative heavy pollution.
Keywords:reservoirs  macroinvertebrate  water quality bioassessment
