Abstract:: To find out the difference of heavy metals in soils grown different trees, the contents of Al, Cd, Cr, Cu, Fe, Mn, Pb, V, Zn in the ginseng growing in soils of forests with elm, pine, poplar, and juglans, respectively, were detected and analyzed. The results are as follows. There were great differences in soil heavy metals under different trees; the CV of Cu was the greatest among between different trees with regard to total metals, which is 0.33, the CV of Fe was the greatest in terms of the available metals between different trees, which is 0.57; the content of total Cd exceeded the second level criterion of Standard of Soil Environment (GB15 618—1995), which was 0.390 mg/kg; the available contents of Cd, Cu, Fe, Pb, V, Zn were both higher in juglans soils than any soils growing the other trees, the available contents of Al, Cr were both higher in pine soils than any other trees, the available contents of Cd, Cu, Fe were both lower in poplar soils than any other trees. The enrichment factors of Zn, Cu, Cr in ginseng under forest are great, which were 0.445, 0.47 and 0.279, respectively, and the enrichment factor of V in ginseng under forest was lowest between different heavy metals; the SHBI of ginseng under forest were the greatest under juglans and the lowest under poplars. There was a significant positive correlation between the SHBI of ginseng under forest and the available Fe, the correlation coefficient was 0.796, and there was a significant negative correlation between the SHBI of ginseng under forest and the available Mn, the correlation coefficient was 0.76.
