The characteristics of heavy metal spacial distribution in 100,100,300 m three belt transect and different depth 0~5,5~10,10~20,20~30 cm in soil,for Cr,Cu,Zn,Cd,Pb,As and Hg were analyzed of the pasture soil in Dongming Coal Mine soil accumulated place,which was evaluated by soil environment quality standard(GB15618-1995). The results showed that the content of Cr,Cu,Zn,Cd,Pb,As and Hg in same depth of different belt transect was changing for different distance and depth;The content of soil heavy mental of different depth in the same belt transect was changing for the different depth. The content of heavy mental was increasing in the soil, heavy mental metastasis and accumulation to the inner of the soil.
