Abstract
A study concerning eutrophication evaluation of Mianhuatan Reservoir was carried out from January to May in 2012.The nutrition state of Mianhuatan Reservoir was evaluated by using the comprehensive nutrition state index.Results indicated that most of water bodies in Mianhuatan Reservoir were Ⅳ to Ⅴ level of water quality standards,and were in a mesotrophic state.Waters in some areas showed a trend of eutrophication.The primary contaminants were coastal livestock farming and sewage pollution.The structure of fish population in the reservoir was maladjusted.The balance of water ecological system was on the verge of damage.
