滇池水质演替趋势及防治对策分析

秩相关系数检验表明,近十年来滇池内外湖中总氮、总磷、高锰酸盐指数均无显著性变化,水体始终受到富营养化及有机污染.治理滇池应在逐步实施控制点源、面源、内源与截污的基础上,与昆明的城市发展结合起来,建设湿地、水生植物等在内的湖滨带复合生态体系.

Succession Tendency of Water Quality of Dianchi Lake and Prevention Countermeasures

Correlation coefficient test shows that, there is no obvious change in total N, total P, permanganate index in both inner and outer Dianchi lake, and water is always subject to eutrophication and organic pollution. It is believed reasonable for Dianchi treatment that, on a basis of pollution interception and gradually controlling pollution from point-source, non-point-source, inner-source, to build compound ecological system (including wetland, hydrophytes) at lake shore belt.
