摘要： 以典型的边境县盈江县为例，建立耕地质量评价体系，并进行基本农田布局优化，以期保障粮食安全及促进西部边境区域耕地可持续利用。利用层次分析法、专家打分法及GIS软件，结合盈江县实际情况及所构建的评价指标体系对盈江县耕地进行评级，并根据评价结果进行基本农田的划分。结果表明：将盈江县耕地划分为4个等级，其中一等耕地占22.92%、二等耕地占37.46%、三等耕地占27.55%、四等耕地占12.07%，并提出了改善耕地质量的措施及盈江县基本农田的布局方式。在耕地分级的基础上进行基本农田的划分，满足了盈江县的基本农田确保数量、提升质量的要求，同时将来也可以为进一步提高基本农田的生产力提供理论依据。

Abstract: In order to ensure food security and promote the sustainable use of cultivated land in western border region, quality evaluation system of cultivated land was established and basic farmland layout was optimized in typical border county Yingjiang. The farmland was classified by the method of analytic hierarchy process, expert scoring and GIS, combined with the actual situation and the evaluation index system of Yingjiang County, basic farmland partition was conducted by the evaluation results. The results showed that the farmland could be divided into 4 grades, the first- grade farmland occupied 22.92% , the second- grade farmland occupied 37.46%, the third-grade farmland occupied for 27.55% and the fourth-grade farmland occupied 12.07%, and the measures for farmland quality improvement and the basic layout of farmland were proposed. Basic farmland partition based on farmland classification met the requirements of quality and quantity of farmland in Yingjiang, it could also provide theoretical basis for the further improvement of basic farmland productivity.
