The invention discloses a remediation method of stabilization / solidification of lead-polluted soil. According to the method, a FeSO4 solution is added to the heavy metal lead-polluted soil, so that H+is generated through oxidization of the Fe2+, thus reducing pH value of soil, and promoting the conversion of instable lead in the soil into an effective state; then biochar and phosphate are added to the heavy metal lead-polluted soil, so that through adsorption, complexness, kation exchange, precipitation and the like between the biochar and phosphate and lead ions, the lead of effective stateis further converted into a lead compound in a stable residue state, thereby reducing the bio-availability of the heavy metal, reducing the content of the heavy metal in effective state in soil, and achieving adsorption and stabilization treatment of lead.
