Abstract
Physico-chemical data , phytoplankton species and densities are determined from 2011 to 2014 in Tangxi Reservoir . The status of water pollution is evaluated based on Eutrophication index , Shannon -Wiener index , and analysis characteristics of phytoplankton distribution .The results show that the eutrophication degree of Tangxi Reservoir is in high level , close to rich nutrition.The total number of cyanobacteria , green algae, Diatoms accounted for 95% of hytoplankton.The risk of cyanobacterial blooms is great .Nitrogen and phosphorus are the main pollutant indices .The main pollution sources is from nearly 300000 people living in the upstream and the pollution from planting eucalyptus .关键词
