Vertical distributions of major and trace elements in soils formed on the Yuanyang lake nature reserve area, the northeastern Taiwan, China
Three soil pedons were selected in the Yuanyang Lake Nature Reserve Area, the northeastern Taiwan, including one Histosols (Haplohemist), one Ultisols (Hapludults), and one Spodosols (Haplorthods), to (1) investigate the soil type, and (2) to establish and compare the vertical distribution of major and trace elements between different soil types. The results indicated that the soil genesis was mainly affected by microenvironment. The content of soil elements followed: Spodosols>Ultisols>Histisols. The Al and Si contents were the highest with the cumulative amount reaching>90％. The higher organic matters in pedon YYL-1 seemed to retain more cations in the organic layer, including Cr, Ca, Pb, Cu, Zn, and As. The distribution of elements with soil depth indicated that intensive illuviation has resulted in a progressive increase in element content with depth YYL-2 profile. The high content of Fe and A1 in the Bsm horizon of pedon YYL-3 indicated the characteristics of Bsm formation.
