Abstract：The benthos community of the the Tanjiang River were investigated in March and July, 2011. Diversity index was used to evaluate the water quality and Index of Biotic Integrity was established to assess health condition of the Tanjiang River. There were 8sections (20sampling points in total) of the Tanjiang River were selected for sampling and 29benthos species were collected in total. Index of Biotic Integrity was used to rate the water quality of sampling points. Indexs were screening to build B-IBI index system which was appropriated for Tanjiang. The indexs system includes Diversity index, species number, Margalef richness index, Evenness index and the percentage of snailsin molluscs. Results of integrity rating were related to the pollution and habitat of sampling points. The high, good, medium, bad and worse integrity ratings were 5, 3, 4, 5and 3respectively. The health condition of the Tanjiang River in summer is better than that in spring.
