Although some major projects have been implemented in the sand areas, but the scientific and technical principles of integrated management are not clear and have not been fully reflected in these projects. Considering such cases, we discussed the challenges, scientific principles, technical principles and implementation priorities of the integrated management of Horqin Sand Land. In Horqin Sand Land, the relationships between forest and farmland, forest and forest, forest and water, farmland and water, forest and grassland, sand land and water, farmland and grassland were not well coordinated, resulting in resource imbalance and low ecologic services. The integrated management should follow scientific principles and laws, including aeolian sand movement law, grassland interface theory, water resource balance theory, biodiversity maintenance theory, landscape ecology theory, and ecosystem services. At the technical level, the principles of water-sediment relationship coordination, landscape design optimization, prevention and control technologies and modes multi-directional synergia, natural and man-made landscapes harmonies, "production-ecological" space layout balance should be highlighted. The key points of integrated management should focus on the function improvement of sand dunes and shelter forests, the efficiency improvement of farmlands and grasslands, the ecological conservation of lakes, the greening and beautification of human settlements, the ecological restoration of engineering projects. This review could provide reference for the integrated ecological environment construction in Horqin Sand Land and the sand areas of northern China.PMID:36601852 | DOI:10.13287/j.1001-9332.202212.026
