摘要
对昆明市主要供水水源松花坝水库、大河水库、柴河水库作了水质现状和富营养化评价，结果为：2005年松花坝水库水质为Ⅳ类，中营养；大河水库水质为Ⅲ类，中营养；柴河水库水质为Ⅲ类，富营养。分析了3个水源地2001～2005年污染指标变化趋势，根据污染分析提出了防治对策。
A survey on water quality situation and eutrophication assessment of main drinking water supply sources in Kunming is conducted. The results show that the water quality of Songhuaba reservoir in 2005 is Ⅳ class, which is mesotrophic, and that of Dahe reservoir is Ⅲ class, which is the same as Songhuaba reservoir, and that of Chaihe reservoir is Ⅲ class, which is eutrophic. Based on trend analysis of the data from 2001 to 2005 in these three reservoirs, countermeasures are pointed out.
