Currently, there are researches about environment-friendly road construction plans led by the Ministry of Construction and Transportation in progress. Therefore, in order to create the revegetation techniques of thin layer-soil combination media hydroseeding measures by actively using native herbs and native woody plants instead of using imported foreign grasses as a concept of sustainable environment-friendly land development, this thesis is going to identify problems that can appear when applying the thin- layer-soil-media hydroseeding measures by the suggested in the "Slope revegetation design and guidelines" proposed by the Ministry of Construction and Transportation, and to propose improvement plans for the problems.To this aim, a seeding mixture selection test was conducted by the goal of slope restoration, and a test group for artificial slope was created. As for a test for June sowing, it was intended to identify appropriate combination quantity by conducting a test that differentiates the combination quantity, and as for a test for September sowing, an artificial slope test was conducted by creating an artificial bank for earth and soil and applying 1~2cm and 3~4cm thickness after differentiating the seed combination volume and slope aspects.
