| 摘要: |
| 据20112013年对上海市31条河流底栖动物的调查结果,对31个生物参数进行分布范围、判别能力以及相关性等进行分析,确定构建上海市河流底栖动物完整性指数(B-IBI)的4个参数:(寡毛类动物+蛭纲)数量百分比、耐污类群分类单元数、双翅目数量百分比和集食者分类单元数百分比.采用比值法统一量纲,将各个生物参数分值加和得到上海市河流B-IBI值.利用构建的B-IBI对上海市31条河流健康状况进行评价,结果表明:31条河流中,有4条河流处于健康状态,8条河流处于亚健康状态,9条河流处于一般状态,8条河流处于较差状态,2条河流处于极差状态;远郊河流健康状态最好,近郊次之,市区最差. |

| Abstract: |
| Form 2011 to 2013, benthic macro-invertebrate assemblages were sampled from 31 rivers in Shanghai City. The analyses of the range of index value distribution, judgment ability and Pearson correlation were analyzed on 31 candidate metrics. Four biological metrics including relative percentage of Oligochaeta and Hirudinea, number of tolerant taxa, percentage of Diptera number and percentage of collector taxa richness were selected for establishing Benthic Integrated Biotic Index (B-IBI).The values of metric were calculated by ratio scoring method, and B-IBI was obtained by combining all those 4 indices.According to these established criteria, results showed that among 31 rivers of Shanghai City, 4 rivers were healthy, 4 rivers were sub-healthy, 9 rivers were good-fair, 8 rivers were fair, 2 rivers were poor. The health status was best in rural rivers, followed by suburban rivers, and worst in downtown rivers. |
