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.
