摘　　要：通过对太白山山顶大爷海、二爷海、三爷海与玉皇池等4个湖泊解冻期与冰冻期水体17项常规指标监测,分别利用单项污染指数与综合污染指数对太白山山顶湖泊水质现状进行评价,并对不同时期水质差异进行分析。结果表明太白山山顶湖泊总氮超标严重,总磷、氨氮与汞含量也出现超标现象,其他指标均符合我国地表水环境质量Ⅰ类标准。综合污染指数显示4个湖泊均属于清洁水体,清洁度排序为玉皇池>三爷海>二爷海>大爷海。冰冻期湖泊水质优于解冻期。Based on the monitoring of 17 routine indexes of 4 lakes at the top of Taibai mountain including Daye lake,Erye Lake,Sanye lake and Yuhuangchi lake during thawing and freezing periods,the water quality of the lakes was evaluated by using the single pollution index and the comprehensive pollution index respectively,and the difference of water quality in different periods was analyzed.The results showed that the total nitrogen in the lakes exceeded the limit severely,the contents of total phosphorus,ammonium and mercury also exceeded the standard slightly,and the other indexes were in line with the levelⅠof the"Environmental quality standards for surface water"in China.The comprehensive pollution factor indexes showed that all four lakes belonged to clean water,and the cleanness rank as Yuhuang lake>Sanye lake>Erye lake>Daye lake.The water quality of lakes in freezing period was better than that in thawing period.
