Abstract
Land is the all-important resource and material for human survival and development. Healthy, ecological, and highly efficient farmland is the basis of modern agriculture. Eliminating land use obstacles and improving crop living conditions are improtant for providing healthy and fertile soils for improved crop varieties. This study intends to address the issues of sandy land consolidation and sustainable use in Mu Us Sandy Land area. Soil reconstruction with natural red clay or loess is an economical and ecological method for sandy land improvement. Complex technology systems and patterns are constructed through land consolidation engineering experiments, including sandy land structuralization consolidation, crop varieties optimized selection, and water and fertilizer precision management. Sandy soil oriented consolidation will provide scientific supporting for degraded land consolidation and modern agrciultural development. In the furture, a related land engineering technonolgy system and a whole-chain land project management mechanism should be intensified through soil reconstruction, farmland building, and soil improvement from micro, meso, and macro level, respectively.
