| Abstract: | Studies on benthic macroinvertebrates from the Beijiang River were carried out between 1981-1982. It has been found that the community of benthic macroinvertebrates was mainly composed of molluscs , aquatic oligochaetes and aquatic insects.Among them Corbicula fluminea (Moll-usca)and chironomids (Insecta) were especially abundant. The data coll-ected from 7 sampling stations set up in the river have been used for calculating Trent biotic index, Chandler's score and Shannon-Wiener diversity index. BaSed on a biological assessment of water quality, the Beijiang River is considered as being lightly polluted on the whole. |
