摘要
本文以叶绿素、总磷、总氮、高锰酸盐指数和透明度等表征富营养化的指标作为评价因子,综合评价和分析了滇池水体富营养化变化特征。在此基础上,总结了过去滇池水体富营养化的防治措施,指出滇池污染治理应围绕水污染控制、水资源开发利用和生态恢复三大问题进行环境工程治理和生态环境治理。
The authors adopted the nutrient indexes, i.e., Chlorophyll-a （Chla）, total phosphorus （TP）, total nitrogen （TN）, chemical oxygen demand （CODMn） and transparency as the evaluating factors in order to synthetically evaluate and analyze the characteristics and causes of eutrophication phenomenon of the Dianchi Lake in Kunrning City. The control measures, which have been applied in the past, were summarized in detail. The three key issues ofDianchi Lake problem including water pollution, water resource scarcity and ecology degradation were discussed. The suggestions about environmental control and ecological restoration measures should be formulated based on the three aspects.
