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.%土地是人类赖以生存与发展的重要资源和物质基础, 现代农业的发展依赖于健康、生态、高效的土地.消除退化土地的利用障碍, 改良作物生长环境, 为不同作物生长需求提供最适宜的"土地配方", 是当前面临的主要问题.针对毛乌素沙地区(榆林) 沙化土地整治与可持续利用问题, 利用红黏土、黄土与沙土的物理互补性, 对沙化土地进行结构性整治, 构建沙化土地整治土体优配和现代农业良种优选的复合技术体系, 实现"沙化土地的订单式整治", 为毛乌素沙地区(榆林) 退化土地整治与现代农业的耦合发展提供科技支撑.未来应重点加强土地工程链研究, 创建全链式土地工程管理机制, 实现微观土地复配、中观土体营造和宏观土质改良工程的技术化和标准化.
