英文摘要	Ferns (Dicranopteris linearis) and soils, sampled from four rare earth mining areas and one non-mining area locating in South Jiangxi region, were chosen for analysis of 15 rare earth elements (REES) by inductively coupled plasma-mass spectrometry ICP-MS). The fern samples were divided into 4 parts: root, stem, petiole, and lamina. The soils of the same sites were also sampled, and 4 soil layers were observed at the profile: A (0-20 cm depth), B (20-150 cm depth), C (150-400 cm depth), and D (rock). The distribution patterns and transportation characteristics of REES of different soil layers and of different parts of D. linearis were studied. The results showed that in the soil layers, the Sigma REE (the sum of the concentrations of 15 REES) of A layer, as well as B layer were lower than that of C layer, but Ce was relatively concentrated in A layer. The Sigma REE of different parts of D. linearis were lamina, root > stem > petiole. The REE distribution patterns of D. linearis root were similar to the total REE distribution patterns of the A layer of their host soils, especially to the soluble REE distribution patterns of the A layer of their host soils. The REES were fractionated in their transportation in D. linearis. The abundances of heavy rare earth elements (HREEs, Gd to Lu and Y) in the stem, petiole, lamina are lower than those in the root.
