Abstract: This paper takes the typical high and steep slopes in the Xishan mining area of Lingdi village, Luquan district, Shijiazhuang city as the object.According to the two slope micro-topography characteristics of slope and roughness, it is divided into areas, and three methods are used for application research:direct guest soil spraying, net guest soil spraying, and cell guest soil spraying.The research shows that by making full use of the micro-top ography features such as slope and roughness, and adding process methods such as hanging nets and cells, the retention of guest soil on the slope can be effectively improved, and the effect of slope ecological restoration can be improved.From the comprehensive consideration of technical feasibility and economic rationality, for soil slopes or rock slopes with a slope of less than 40°, direct sprinkler sowing can be preferred; for rock slopes with a slope of 40°-60°, when it has one of the two conditions of rough slope (concave-convex ≥10 cm) or development of micro-steps, direct guest soil spraying can also be used, when the slope is relatively rough (concave-convex degree 5-10 cm), the net guest soil spraying or cell guest soil spraying can be selected; for rock slopes with slope ≥60°and weak slope surface roughness (concave-convex degree < 5 cm), it is not suitable to use guest soil spraying.
