The present invention relates to a method of heavy metal stabilization in heavy metal contaminated soil, in which “in situ iron oxide synthesis” in which iron chloride hydrate is injected into the heavy metal contaminated soil, and heavy metals to be stabilized are leached into pores, to generate iron oxide in the heavy metal contaminated soil, is repeated multiple times, the in situ iron oxide synthesis is repeated while a predetermined period of rest time is provided between the in situ iron oxide synthesis each time, thereby exhibiting a very excellent heavy metal stormwater leaching reduction effect.
