| 摘 要： | 1995 年分别在枯、平、丰水期对洞庭湖的6 个断面底泥进行采样监测,共发现底栖动物58 种,密度为78～544.5 个m2 ,10 种优势种均成聚集分布.采用综合生物污染指数评价水体质量,表明目前整体水质为轻污染,但较1981～1982 年水质明显变差

| Abstract: | During 1995, 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 individual/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 had increased obviously compared with the data in 1981 and 1982, which indicated the water quality had changed adversely. These results coincided with that evaluated by chemical pollution indices. |
