摘　　要：该研究通过对都龙矿区2支流水质、底质进行采样分析,探讨了河流底质、水质中铜、锌的污染特征及其相互关系。结果表明,花石头河水质铜、锌质量浓度远高于天生桥河,2支流都是平水期铜、锌质量浓度高于丰水期。而2支流表层底质铜、锌质量浓度超标严重,且天生桥河高于花石头河。在2个采样期,丰水期底质铜、锌质量浓度高于平水期,即底质中铜、锌质量浓度有随季节推移而下降的趋势,丰水期底质铜、锌质量浓度波动大,平水期趋于平稳。研究还表明,2支流底质中铜、锌质量浓度与水质相应重金属浓度具有负相关关系,即底质铜、锌质量浓度越高,水质铜、锌浓度反而降低。In this paper,based on sampling and analyzing the water quality and sediment from two tributaries of Dulong mine area,the copper zinc pollution characteristics of the river sediment and water quality and their relations were discussed.The results showed that the copper zinc concentration of water in Huashitou river were far more than in Tianshengqiao river,and the copper zinc concentration of average flow period were all higher than of flood flow period＇s in two tributaries.Meanwhile,the copper zinc concentration of the surface layer sediment were beyond national standard seriously and the copper zinc concentration of the surface layer sediment in Tianshengqiao river were higher than in Huashitou.In two sampling periods,the sediment copper zinc concentration in flood flow period were higher in average flow period,that is,the sediment copper zinc concentration became gradually lower and lower with season,in which the sediment copper zinc concentration in flood flow period fluctuated largely and the sediment copper zinc concentration in average flow period turned to steady state.Furthermore,there was negative correlation between the sediment copper zinc concentration and copper zinc concentration of water in two tributaries,that is,the sediment copper zinc concentration were higher,the copper zinc concentration of water were lower.
