The toxic impact of heavy metals contamination on soil have been emphasized in the past year, however, the risk of soil contamination in forest areas cannot be neglected. The purpose of this study is to investigate the concentration and distribution of seven major elements (Na, Mg, Al, P, K, Ca and Fe) and the potential ecological risks of three metals (Mn, Cu, and Zn) induced by human activities after the conversion from natural forest (NF) to plantation forest (PF). The result showed that the average metal concentration followed the order: Fe>K>Al>Na>Ca>Mg>P>Mn>Cu>Zn. Mn and Cu were strongly influenced by soil disturbance. All sampling sites were considered as slight pollution (1≤PI<4) and as low potential ecological risk index for individual metals (<40), and the environment (RI<65). Contamination with Mn, Cu and Zn was uncontaminated to moderately contaminated (0
