Firstly,the species composition and dominant species of phytoplankton were analyzed,and then the water quality of the moats was evaluated by cell density,water-quality indicator species,biodiversity index method,and saprobic index method. The results show that there were 114 species of phytoplankton in the moats of Dinghai District in spring,belonging to 70 genera,38 families,and 7 phyla,of which Bacillarophyta,Chlorophyta and Cyanophyta were dominant; the main dominant species were Synedra acus,Aphanizomenon flosaquae,Microcytis flos-aquae,etc. The cell density of phytoplankton in the moats ranged from 1.07 million to 13.7 million cells/L. Shannon-Wiener diversity index,Margalef richness index,Pielou evenness index,and saprobic index averaged 0.93,2.53,0.12,and 2.61 respectively. On the whole,river water in the moats of Dinghai District was polluted seriously,but there was no obvious difference between the four rivers in water pollution.展开更多
