Abstract: The concept and characteristics of engineering designs on sustainable agricultural land consolidation project were discussed in this paper. Principles,basic methods and procedures of engineering designs on agricultural land consolidation project were put forward,which were successfully adopted for designing agricultural land consolidation in Xuemeiyang region of Changtai County,including diversity designs of sustainable land use,engineering designs of soil improvement,roads,ditches,and drains for protecting existent animal environments,and design of ecological shelter-forests in farmland.Moreover,from sustainable economic,ecological and social points,the results of these engineering designs were evaluated based on fouteen important indexes. After carrying out these engineeringdesigns,the eco-environments and agricultural production conditions were significantly improved,and the farm income was increased in planned regions.
