镜泊湖富营养化评价及预测研究

摘要

Eutrophication has become the most important problem of lakes and reservoirs in our country. Due to different eutrophication decision factors of different lakes, the main pollution factors in the Jingbo Lake were confirmed by the analytic principal component method. According to the main influencing factors, the eutrophic state of Jingbo Lake was evaluated by trophic status index, and the potassium permanganate index and total phosphorus were predicated. Based on the eutrophication assessment and prediction, the suggestions of the prevention and control measures of pollution were brought.%富营养化已成为我国湖泊、水库的重大环境问题。由于不同湖泊富营养化发生的决定因子不同，本文通过主成分分析法进行镜泊湖水质污染主要因子的筛选，根据主要影响因子采用营养状态指数法进行富营养化评价，并对镜泊湖流域高锰酸盐指数和总磷进行预测，根据富营养化评价和预测结果，提出镜泊湖污染防治措施。
