The invention provides a method for carrying out a stabilization obstruction on soil with slight heavy metal pollution, and aims to solve a problem of no feasible treatment method for heavy metal slightly polluted soil characterized by large area and huge cubic meter of earth. Main points of the invention lay in that a medicament layer, a non-woven fabric layer, a filling layer and a cover layer are successively laid on the soil with slight heavy metal pollution; the filling layer contains one or all of an organic filling material and an inorganic filling material; the cover layer refers to non-woven fabric or polyethylene membrane. The present invention has beneficial effects that because of convenient and low cost construction, the method is suitable for heavy metal slightly polluted soil characterized by large area and huge cubic meter of earth.
