The invention provides a remediation method of soil polluted by heavy metals. The method is technically characterized in that the heavy metals in the soil are fixed by using properties of adsorption and solidification of red mud on the heavy metals; simultaneously, the red mud cooperates with plants which are planted on the surface of the soil and are capable of absorbing the heavy metals so as tofurther enhance the effect of removing the heavy metals, the plants are removed, then the heavy metals are removed, the plants are carbonized and leached, then the heavy metals are separated from carbon; in addition, the red mud is capable of releasing excessive -OH ions into the soil, enabling inorganic phosphorus in the soil to be hardened and enabling the alkalinity of the soil to be increased; the red mud is also compounded with phosphorus solubilizing bacteria and EM bacteria liquid; the phosphorus solubilizing bacteria have the effects of avoiding reduction of the content of free-statephosphorus in the soil and simultaneously avoiding rapid increase of the alkalinity of the soil.
