通过测定茅尾海红树林湿地3种红树植物（桐花树、秋茄和老鼠鷚）的Cu、Zn、Cr、Ni、Pb、Cd、Hg、As等8种重金属元素含量，分析了重金属元素在该红树林湿地植物不同组织（根、茎、叶）的分布特征、累积和迁移能力。结果表明，该红树林湿地不同植物对金属元素的吸附能力存在一定差异：桐花树Zn＞Cr＞As＞Pb＞Cu＞Ni＞Cd＞Hg；秋茄Zn＞Cr＞Cu＞As＞Pb＞Ni＞Cd＞Hg；老鼠鷚Zn＞As＞Cr＞Cu＞Pb＞Ni＞Cd＞Hg。不同的植物组织对不同的重金属元素的累积能力表现不同，但3种红树植物组织对Hg的累积能力均表现为叶＞根＞茎。红树植物对8种重金属的累积顺序为桐花＞秋茄＞老鼠鷚，对Cd的富集系数最大。

Heavy metals such as Cu,Zn,Cr,Ni,Pb,Cd,Hg,As from 3 plants (Aegiceras corniculatum,Kande-lia obovata and Acanthus ilicifolius)in the mangrove were measured in Maowei Gulf,and the distribution,the en-richment and migration ability of heavy metals were analyzed in different tissues (roots,stems and leaves).Re-sults show that the adsorption ability of metal elements from different plants in the mangrove is different.The con-tent of heavy metals show Zn>Cr>As>Pb>Cu>Ni>Cd>Hg in Aegiceras corniculatum,Zn>Cr>Cu>As>Pb>Ni>Cd>Hg in Kandelia obovata and Zn>As>Cr>Cu>Pb>Ni >Cd>Hg in Acanthus ilicifolius.The concentration of Hg in the mangrove plants was leaves>roots>stems and other heavy metals existed differently in different tissues.The enrichment of three mangrove plants was Aegiceras corniculatum>Kandelia obovata>Acan-thus ilicifolius.The enrichment coefficient of Cd was big for mangrove plants.
