摘要
1993~ 1997年对黄河三角洲 8条河流、 3个水库和 1个湖泊水质连续 5年进行了监测 ,1996~ 1997年对淡水鱼类多样性开展了同步系统调查。水质评价结果 :6条河流为重污染 ,2条河流为严重污染 ,2个水库轻污染 ,麻大湖严重污染。淡水鱼类共鉴定出 10 2种和亚种 ,隶属于 9目 17科 65属 ,占山东省淡水鱼类总种数的 89%。水质污染已导致鱼类多样性减低 。
The water pollution of 1 lake,3 reservoirs and 8 rivers in the Yellow River Delta was consistently monitored from 1993 to 1997,and the fresh water fish species diversity was systematically investigated from 1996 to 1997.The evaluations obtained are as follows:2 reservoirs are lightly polluted,6 rivers are seriously polluted,and the Mada Lake and 2 rivers are very seriously polluted.102 species and subspecies of fresh water fish have been identified,belonging to 9 orders,17 families and 65 general,accounting for 89 % of all the fresh water fish species of Shandong province.Water pollution has resulted in the decrease of fish secies diversity and even extinction of fish species in a few rivers.
