摘　　要：对某冶炼厂生产区周围污染土壤中锌的形态分布进行了分析,并且研究了不同生产区重金属的生物活性,计算了重金属锌对生物有效性系数和重金属迁移系数。实验结果表明,该厂不同生产区周边污染土壤中锌的形态分布规律基本相同,即RES(Fe-Mn(OM(CA(EXC、WS;A区和B区锌的生物有效性系数大小顺序均为:K3>K2>K1;而A区与B区的生物可利用性相比较而言,K1(B区)(K1(A区),即B区的生物有效性大于A区;B区锌的迁移能力大于A区。According to the contaminated soil in a smelter, the distribution state of zinc was analyzed, the biologic activity of heavy metal in diverse productive areas was studied and the biologic valid coefficients of Zn and the mobility coefficients of heavy metal were calculated. The results showed the distribution orders of zinc （ RES 〉 Fe-Mn 〉 OM 〉 CA 〉 EXC, WS） in contaminative soils of diverse productive areas were nearly same. The biologic valid coefficient in both A areas and B areas were K3〉K2〉K1, while the biological validity K1 （B） 〉 K1 （A） ,so the mobility ability of zinc in B areas was higher than that in A areas.
