摘要
1993～1997年对黄河三角洲内8条河流、3个水库和1个湖泊水质连续5年监测,1996～1997年对淡水底栖动物多样性开展了同步调查.水质评价结果:2条河流严重污染,6条河流重污染,麻大湖严重污染.淡水底栖动物共鉴定出69种,隶属于38科62属.水质污染已导致底栖动物多样性减低.
Continuous monitor was carried out from 1993 to 1997 on the water quality of 8 rivers,3 reservoirs and 1 lake in the Yellow River Delta. In pace With the monitor,a systematic investigation about the species diversity of freshwater benthic maeroinvertebrates was performed from 1996 to 1997. The result of the water quality evaluation is as following. 2 rivers are severely polluted,7 rivers are heavily polluted and Mada Lake is severely polluted, 69 species of freshwater benthic macroinvertebrates are identified. They are subordinate to 38 families and 62 genera. Water pollution has decreased the species diversity of benthic.
