根据2006年-2010年万佛湖的水质监测数据,选用pH、溶解氧、五日生化需氧量、高锰酸盐指数、氨氮、汞、铅、挥发酚、石油类、总磷、总氮等11项污染指标,采用综合评价方法对万佛湖的水质变化进行了分析。结果表明：＂十一五＂期间万佛湖的水质综合污染指数由2006年的3.47下降到2008年的2.92,而后又上升到2010年的4.00,水质总体上趋于稳定。但是由于农村和农业废水排放量的增加,总氮和总磷是影响整个水质的主要因子,有明显的上升趋势,须引起有关部门的注意。

According to the local monitoring data of Wanfo Lake in Luan City from 2006 to 2010,eleven main pollutant indices including,pH,dissolved oxygen,BOD5,permanganate index,ammonia nitrogen,Hg,volatile hydroxybenzene,petroleum,total phosphorus（TP）,total nitrogen（TN） were selected to assess the water quality of Wanfo Lake based on pollution index method.The result showed that the comprehensive pollution indices decreased from 3.47 in 2006 to 2.92 in 2008,and then rose from 2.92 in 2008 to 4.00 in 2010,indicating that the water quality of Wanfo Lake was stable during the Eleventh Five-year Plan.However,the pollution indices of some pollutants such as TN and TP increased obviously due to uprising discharge amount of rural and agricultural sewage,which should receive more attention from the government.
