Abstract: To grasp the quality of the high standard basic farmland and scientifically plan the spatial layout of high standard basic farmland, and to reasonably arrange for the development and construction timing, this study effectively selected and quantified important factors to build internal quality evaluation system, and used the external social and economic impact gradual correction factors and the comprehensive quality evaluation for the town of Tongjing in the district of Yubei basic farmland, and explore Tongjing Town high standard basic farmland’s construction space layout and scheduling, for making a high standard to maximize the overall efficiency of basic farmland after completion. The empirical results showed that Tongjing Town had 355.96 hm² suitable farmland for high-standard basic farmland construction, combined with a high standard of basic farmland construction of Yubei district targets and financing conditions, Tongjing Town high standard basic farmland construction could be divided into 3 periods, recent layout arrangement in the eastern region, the construction scale of 114.52 hm²; interim distribution arrangements in the southern and northern regions, the construction scale of 176.67 hm²; forward layout arrangement in the western region, the construction scale of 64.77 hm².
