Objective To provide technical guidance for ecological restoration and forestry ecological engineering construction in the Loess Plateau. Methods The technical problems existing in the “Conversion of Cropland to Forestland” project in this area were investigated and analyzed. Results The plan of vegetation restoration for degraded cultivated slope in northern Shaanxi was put forward, including the selection and afforestation technology of fine tree and grass, the horizontal and vertical configuration of tree species, the technology of drought resistance afforestation and mixed forest construction centered on water storage and soil moisture conservation , And evaluated the expected ecological and social benefits. Conclusion The scheme is instructive for the restoration of ecological environment and the construction of forestry eco-engineering in the Loess Plateau.
