中文摘要：Yan，C.，中国地质大学，和Liu，J.，2013.红树林对福建漳江口沉积物中稀土元素水平和垂直分布的影响。为研究红树林环境对河口沉积物中稀土元素分布的影响，采集了张江河口红树林、林缘和泥滩的表层和柱状沉积物样品。用电感耦合等离子体质谱法测定了表层沉积物和岩心样品中稀土元素的含量。轻稀土元素比重稀土元素更富集，相对于北美页岩组合，沉积物中铕的负异常相对较弱。不同采样点和采样点间稀土元素含量差异显著，其顺序为：红树林>林缘>滩涂。河口区稀土元素主要来源于漳江流域的陆源风化物。红树林环境影响沉积物的理化特征，从而影响稀土元素的空间分布。红树林根系活动改变了岩芯中稀土元素的垂直分布。红树林对沉积物中稀土元素的水平和垂直分布具有重要的控制作用。
ABSTRACT Zhang, R.; Yan, C., and Liu, J., 2013. Effect of mangroves on the horizontal and vertical distributions of rare earth elements in sediments of the Zhangjiang estuary in Fujian Province, Southeastern China. To examine the influence of the mangrove environment on the distribution of rare earth elements (REE) in estuarine sediments, surface and core sediments were collected from regions of mangrove forest, forest fringe, and adjacent mudflat in the Zhangjiang estuary, SE China. Concentrations of REE were determined in surface sediments and core samples using inductively coupled plasma mass spectrometry. Light REE were more enriched than heavy REE, with a relatively weak negative europium anomaly with respect to the North American shale composite in sediments of the Zhangjiang estuary. Significant differences for REE were found among sampling sites and locations, following the order mangrove forest, to forest edge, to mudflat. The main source for REE in the estuary is the weathered continental materials from the Zhangjiang River drainage basin. The mangrove environment affected the physicochemical features and thus affected the REE spatial distributions in sediments. Vertical REE distributions in core samples were altered by mangrove root activity. Mangroves played a significant role in controlling the horizontal and vertical distribution of REE in sediments of the Zhangjiang estuary.
