| 摘 要： | 以自然条件复杂的海南岛北部红树林区调查资料为基础,通过分析红树林区沉积物中微量元素的含量和垂直变化特征,探讨了微量元素空间分布的控制因素。结果表明,沉积物中微量元素的平均质量分数排序为：Zn〉Cr〉N i〉Cu〉Pb〉Co〉As〉Mo〉Hg,微量元素在不同的区域含量不同,东寨港红树林区和清澜港红树林区中表层沉积物中的微量元素含量较高,而新盈港红树林区的相对较低。新盈港红树林区除了As元素外,几乎所有的表层沉积物微量元素都高于下层沉积物中微量元素的含量,这说明微量元素在新盈港红树林区表层沉积物中富集;东寨港红树林区,下层沉积物中6种微量元素高于表层沉积物中微量元素含量,说明表层沉积物受淋溶作用影响大,微量元素在其下层富集;清澜港红树林区,Cd、Cr、Zn在沉积物下层富集,As、Co、Cu、Hg、Ni、Pb等元素在沉积物表层富集。

| Abstract: | A series of samples collected during the survey on sediments of mangrove areas on northern Hainan Island was analyzed to reveal the content and vertical distribution of trace elements,the control factors of the element' space distribution were discussed.The results showed that the average concentration of trace elements in sediments of mangrove areas on northern Hainan Island sorts for Zn> Cr> Ni> Cu> Pb> Co> As> Mo> Hg.Trace elements have different content in different regions,the trace element of surface ... |
