摘　　要：利用相关分析和通径分析考察了海南岛东寨港海水中重金属含量与海域pH、盐度之间的关系。相关分析表明,Ni、Zn、Hg含量与海域pH之间呈极显著或显著负相关;As含量与海域pH之间呈极显著正相关;Ni、Zn、Cu与海域盐度之间呈极显著或显著负相关;As与盐度之间呈极显著正相关。通径分析表明:重金属含量对海域pH的直接作用大小顺序为As>Ni>Hg>Zn>Cu>Cd>Pb;重金属含量对海域盐度的直接作用大小顺序为Ni>Pb>Cu>As>Zn>Hg>Cd。The relationship between heavy metal content and pH,salinity respectively in the sea area of Dongzhai Harbor of Hainan Island was studied by correlation analysis and path analysis.The result of correlation analysis showed that there was an extremely significant or significant negative correlation between content of Ni,Zn,Hg and pH of sea area respectively,as well as between content of Ni,Zn,Cu and salinity of sea area respectively,and there was an extremely significant positive correlation between content of As and pH,salinity respectively of sea area.The result of path analysis showed that,the order of direct effect of heavy metal on pH of sea area was As>Ni>Hg>Zn>Cu>Cd>Pb,and the order of direct effect of heavy metal on salinity of sea area was Ni>Pb>Cu>As>Zn>Hg>Cd.
