中文摘要：

红树植物拉关木（Laguncularia racemosa）是近年我国新引种的速生海岸防护林树种。通过对拉关木的根、茎、叶、果实及土壤中的Zn、Cu、Cr、Cd和Pb等重金属含量进行的分析,研究了福建漳州龙海浮宫镇拉关木对某些重金属的净化能力。结果表明：红树林拉关木不同部位对不同重金属富集吸收的能力大小均不同,其中拉关木的根对Cu与Zn的富集吸收效果最为明显。

英文摘要：

Laguncularia racemosa （mangrove） is a new introduced fast growing protective forest species in coastal land. Through collecting roots, stems, leaves, fruits of mangrove and soil, content and distribution of heavy metal, Zn, Cu, Cr, Cd and Pb in soil and plant systems were determined. Distribution, accumulation, migration and reserves of heavy metal in soil plant system were analyzed. The possibility of Laguncularia racemosa on purification for heavy metal were explored. Result shows that enrichment capacity in different parts of Laguncularia racemosa on different heavy metals were different. Enrichment effect of roots of Laguncularia racemosa on Cu and Zn is most obvious.
