摘　　要：对粤北大宝山铁龙尾矿库断面沉积物中重金属各化学形态分布规律进行调查和生态风险评价,结果显示,沉积物中Cd和Pb达到极强污染水平;底泥中重金属的生物有效性由高到低依次为Mn>Zn>Ni>Cd>Pb>Cu,其中底泥p H可能是影响锰形态分布的关键因素。To explore chemical form distribution of Mn, Ni, Cd, Pb, Zn, Cu and ecological risk assessment of the hiatus in sedimentation at acid mine drainage of Tielong tailings located northern Guangdong＇s Dabaoshan. The result indicated that the sediment was polluted by Cd and Pb seriously and reach strong pollution level. The order of biological availability for 6 kind of heavy metal element from high to low is Mn, Zn, Ni, Cd, Pb, Cu. The p H of sedimentation at acid mine drainage of Tielong tailings maybe the major effect factor of Mn chemical form distribution.
