Combined stony desertification ecological restoration method

The invention discloses a combined stony desertification ecological restoration method. The method includes steps: S1, determining a stony desertification site and a stony desertification degree, adjusting measures according to local conditions, acquiring explicit factors including existing site gradient, local climate, local vegetation and the like, performing unified planning and designing of planting grooves and drain ditches, and performing parametric slope-to-terrace modification on land; S2, composting by adopting organic wastes such as sewage treatment excess sludge, garden pruning wastes and the like to recycle the pollution wastes; S3, compounding according to different ratios and different plants, and proportionally mixing compost with original soil without fertility so as to achieve an expected effect of fertility recovery of the soil. The method has advantages that in stony desertification control, sewage treatment excess sludge is adopted for composting, zeolite powder isused in a composting proc
