An environment-friendly slope reinforcement method using a pedestal is provided to facilitate setting up an environment-friendly incline easily because construction is possible in any incline. An environment-friendly slope reinforcement method using a pedestal comprises: a step which anchors polygonal or circular supports(1) on the construction slope(10) with either a large nail, a pile(2) or an anchor bolt at a constant interval; a step which forms a soil layer(3) by covering soil and sand between the supports; and a step which covers the soil layer with vegetation soil then covers it with a thin mat. The support is either timber, plastic or concrete column. The thickness of bracket is 10 to 30cm. The length of the support is 200 to 300cm in case of being used for the vertical support(1") and 500 to 1000cm in case of horizontal support(1').
