| 摘 要： | 1 995年枯水、平水、丰水期对洞庭湖设 6个断面进行采样 ,共采到底栖动物 58种 ;其密度变幅为 78～ 544 .5个 /m2 ;1 0种常见种均成聚集分布。采用综合生物污染指数评价水体质量 ,结果显示洞庭湖整体水质受到轻度污染 ,评价结果与化学污染指数评价结果一致 ;各采样断面综合生物污染指数均明显大于 1 981～ 1 982年的测量结果 ,表明水体质量变差

| Abstract: | The investigations of zoobenthos were carried out in different seasons in 6 sections in Dongting Lake,and 58 species of zoobenthos were observed.Zoobenthos density ranged from 78 to 544.5 ind/m 2,and 10 common species displayed accumulative distribution.The results of biological assessment of water quality showed that the lake was slightly polluted,its integrated biological indices increased obviously compared with the data in 1981 and 1982,which indicated the water quality changed adversely.These results coincided with that evaluated using chemical pollution indices. |
