摘　　要：采用潜在生态风险指数法,以华南滨海盐土环境背景值为参比值,对近20年海南清澜港红树林湿地沉积物重金属污染状况进行评价。结果表明:各样地单一重金属平均含量(W)顺序均为Cr>Zn>Pb>As>Cu,重金属总含量(样地平均值总量)顺序为W(下坡村)>W(白头尾村)>W(官园)>W(丹场村)>W(港东村)>W(霞场村);各样地Ei r平均值顺序为As>Pb>Cr>Cu>Zn,RI值顺序为下坡村>白头尾村>官园>丹场村>港东村>霞场村;各样地生态危害程度均为轻微;下坡村和白头尾村样地重金属平均含量及生态危害程度均明显高于其它4个样地,产生生态危害的主要重金属污染物为As,其次为Pb。Using the potential ecological risk index,the heavy metal pollution of mangrove sediment in nearly 20 years is evaluated. The result shows that average content of single heavy metal is sequenced as Cr > Zn > Pb > As > Cu. The total content of heavy metal is sequenced as Wxiapo village> Wbaitouwei village> Wguanyuan> Wdanchang village> Wgangdong village> Wxiachang village. The average value of plots is sequenced as As > Pb > Cr > Cu > Zn. The RI value is sequenced as Xiapo village > Baitouwei village > Guanyuan > Danchang village > Gangdong village > Xiachang village. The ecological hazards of each site are slight. The average content of heavy metal and ecological risk of Xiapo village and Baitouwei village is significantly higher than the other four plots. The main ecological risk of heavy metal pollutant is As,followed by Pb.
