可持续农地整理项目工程设计的理论和方法研究——以福建省长泰县雪美洋土地整理项目为例

探讨了可持续农地整理项目工程设计的概念和特点，提出了农地整理项目工程设计的原理、基本方法和设计流程，并以长泰县雪美津项目区为例，进行了促进土地可持续利用的土地利用多样性设计，土壤改良工程设计和有利于保护动物生存环境的生态型道路工程设计，生态型排水沟和灌水渠工程设计以及农田生态防护林工程设计，并对项目工程设计结果的可持续性从生态可持续性，经济可持续性和社会可持续三方面，选择了14个指标进行了评价，结果表明，按工程设计要求实施后，项目区的生态环境有明显的改善，经济收入有较大的提高，公众满意，农业生产条件显著改善，它符合可持续农地整理的基本要求，有助于推进土地整理的健康发展。

Theories and methodologies of engineering designs on sustainable agricultural land consolidation project-A case study of Xuemeiyang land consolidation project in Changtai County,Fujian Province

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.
