The Vertical distribution of six trace elements in different subgroup of Black soils（three subgroups five profiles）in the middle of Jilin province were studied by means of field work,chemicalanalysis and instrument analysis.The result showed that the tested trace elements had different distribution in different parent material profile and soil types.Red parent material had high content of total Zn.Total Cu had little change in different subgroup parent materials,Available Cu had little surface accumulation in typical black soil,while in meadow black soil had obvious leaching,in albic black soil had both biological enrichment and leaching.Total Zn had little change in the each different profile,and it had obvious surface accumulation in both typicalblack soil and meadow black soil,in albic black soil had obvious leaching.Available Zn was significantly correlated to organic material.
