To address the problems of large amount of abandoned land, unused land, and degraded land, the paper analyses three cases of Yucheng, Yan'an and Yulin, and systematically interprets the role of land engineering technology in ensuring land and food security, coordinating rural man-land relationship, and promoting efficient rural land use. It further investigates the relationship between land engineering and rural sustainable development. The paper proposes that the exercise of land engineering can help with rural reconsstruction, and improve rural resilience against external shocks and fluctuations. Land engineering contributes positively to the rural vitalization strategy. Finally, the paper indicates that land engineering should consider rural suitability and adapt to local conditions, and also calls for scientific planning and design.%针对转型期我国乡村发展面临的大量空废土地、未利用土地、退化土地的现实问题, 文章通过对禹城、延安、榆林三个地区的典型案例进行分析, 系统阐释了土地工程技术在保障耕地及粮食安全, 协调乡村人地关系, 促进乡村土地节约集约利用中的作用, 解析了土地整治工程与乡村可持续发展的关系.文章提出乡村土地综合整治工程有利于实现乡村重构, 提高乡村地域应对外界发展环境变化的能力, 是实施乡村振兴战略的有效途径与重要抓手.最后指出土地整治工程的实施应充分考虑乡村地域适宜性特征, 通过科学规划与设计, 因地制宜推进乡村土地综合整治.
