中文摘要：
对漳江口红树林湿地沉积物中4种重金属（Pb、Cd、Ni、Fe）含量空间分布的研究表明，漳江口红树林湿地沉积物中Pb、Fe含量较高，Cd、Ni含量相对较低；林内沉积物的Pb、Cd含量显着高于林外沉积物；在垂岸方向上，表层沉积物中除Ni外其它三种元素含量均表现出从林外到林内增加的趋势；在垂直梯度上，四种元素含量均随着沉积物深度增加而逐渐降低．
英文摘要：
Based on the studies of spatial distribution of Pb, Cd, Ni and Fe in mangrove sediments of Zhangjiang estuary, some conclusions were obtained. High contents of Pb and Fe were found in the sediments, while the contents of Ni and Cd were relatively lower. Different contents were found at different locations of mangrove wetlands, forest sediments had higher Pb and Cd contents compared to sediments of mudflat. The concentrations of Pb, Cd and Fe increased across the tidal flat to the mangrove forest transition. The results indicated that the total metal concentrations decreased with the increase of sediment depth.
