摘　　要：对阳宗海表层沉积物中磷、氟、硫的含量进行了调查,并用单指标标准指数法对污染水平进行了评价。结果表明,阳宗海表层沉积物磷、氟、硫含量的平均值依次为1 041 mg/kg、1 075 mg/kg、2 743 mg/kg。生活、生产污水、工业废气,以及机动船只、网箱养鱼等活动是阳宗海表层沉积物中磷、氟、硫的主要来源。磷、氟、硫的标准指数平均值依次为1.74、1.34、1.31,表明其在沉积物中的积累已经严重影响了阳宗海的环境质量,对高污染地区污染源的控制与沉积物的治理工作亟待实施。The content and characteristics of phosphorus,fluorine and sulfur were analyzed in surface sediments from lake Yangzonghai in Yunnan,China.Single standard index was used to assess the pollution.The results showed that the average concentrations of phosphorus,fluorine and sulfur in surface sediments of lake Yangzonghai were up to 1 041 mg/kg,1 075 mg/kg and 2 743 mg/kg,respectively.It was considered that human activities,such as sanitary waste,production waste,process gas,powerboat,fish culture in net pen were the major polluting sources of phosphorus,fluorine and sulfur in lake Yangzonghai.The mean standard indexes of phosphorus,fluorine and sulfur were up to 1.74,1.34 and 1.31 respectively,which indicated that serious pollution of P,F and S in lake Yangzonghai.Control of pollutant sources and sediment treatment in the high level polluting regions of lake Yangzonghai should be implemented as early as possible.
