摘要
根据1988～2007年滇池水质监测数据，评价了近20a来滇池水体主要富营养化指标的变化趋势，结果表明滇池水体的富营养化程度有逐年加重趋势。根据其时空分布规律分析了滇池水体的富营养化程度及变化趋势。认为昆明市虽然在治理滇池方面作了大量工作，但滇池水体富营养化的问题仍然很突出。
The change trend of eutrophication index of Dianch lake is assessed based on the monitoring data of water quality from 1988 to 2007. The results indicate that the degree of eutrophication in Dianchi lake has become more and more serious. The water quality of Dianchi lake is still very serious although lots of countermeasures on Dianchi lake protection are implemented in recent years.
