China Environmental Science, 2016,36(9)：2791~2799 Abstract ：The Benthic Index of Biological index (B-IBI) was erected based on the related data (macrozoobenthos, water quality and sediment environment) collected from the Tianjin coastal areas of the Bohai Bay during 2009 to 2013 as well as the available research experience. This is the first time to determine reference sites using AZTI marine biotic indices, water quality and sediment quality. Meanwhile, the standard method was employed to select biological indicators and to define the different levels for their thresholds. Thus, the index of biological integrity was developed. The 90% quantile of the IBI values in the reference sites was adopted as the base value and the calculated biocriteria
