摘　　要：对海南岛北部红树林湿地表层沉积物重金属元素进行分析发现,东寨港、清澜港和新盈港沉积物表层中的Cu、As、Zn、Ni、Cr元素含量均高于海南土壤背景值.相关分析、因子分析和聚类分析显示重金属元素Cr、Cu、Ni、Zn相互间具有极其显著的相关关系,反映这些重金属元素有相同或相似的物质来源.According to the study of heavy metal elements in surface sediments of mangrove wetlands in Northern Hain- an Island, it found that the level of Cu, As, Zn, Ni and Cr element in the surface sediments of Dongzhai Harbor, Qinglan Harbor and Xinying Harbor were all higher than the soil background value of Hainan. The correlation analysis, factor analysis and cluster analysis showed that heavy metal elements Cr, Cu, Ni and Zn had significant correlations with each other, which indicated that the heavy metal elements have the same or similar material sources.
