Estuary Health Assessment Using a Benthic-Index of Biotic Integrity in Yangtze Estuary and Its Adjacent Waters
基于底栖动物完整性指数的河口健康评价

A benthic index of biotic integrity(B-IBI) was developed for application in estuaries health assessment of the Yangtze Estuary and its adjacent waters.Benthic macro-invertebrate samples were collected from 41 stream sites(13 non-degraded stations and 28 degraded stations) in the Yangtze Estuary and its adjacent waters in July,2005.The analyses of the range of index value distribution,Pearson correlation and judgment ability were performed on fourteen candidate metrics.Six biological metrics were selected fo...
