In this paper, we study heavy metal transport and distribution of soils around Dong-bo abandoned mine area. Inside the mine, concentration of Cd, Ca, Zn are exceeded soil management standards. Outside of mine, concentration of Pb, as is exceeded soil management standards. Especially, concentration of Pb is higher than soil protection standard of 300㎎/㎏ in S-6 point which is tailing accumulation area. Although heavy metal concentration of mine water was higher than Unsuchon, water contaminated level was lower than soil. 30cm-depth soil is serious in S-6 point, heavy metal transport had influence on Unsuchon. Further more, we used pollution index(PI) to evaluate soil contamination totally, it exceeded standard "1" in S-6 points of surface soil and 30cm-depth soil. So it decided that contamination of heavy metal is more seriously than other sampling points. In contaminated soil, pH and organic contents are lower than non-contaminated soil. Therefore heavy metal concentration has influence on adsorption and retardation of soil by pH and organic contents variation. Moisture contents also encouraged heavy metal transport velocity, but less than pH and organic contents.
