Abstract: The construction of high-standard basic farmland is to ensure food security according to the general plan of land utilization and improve the quality of arable land by land remediation planning within a certain period. We evaluated the quality of cultivated land in Wuyang County and put forward opinions on zoning construction by using analytic hierarchy process and ArcGIS spatial data based on the Regulations for Classification and Grading of Agricultural Land in combining with the actual situation. The results showed that (1) the highest quality score of cultivated land in Wuyang County was 97.2, the lowest was 64.8; (2) the cultivated land in Wuyang County was divided into four types of the core protection, appropriate transfer, key renovation and improvement of returning farmland; (3) the ways to improve the cultivated land quality and build high standard basic farmland were different due to the characteristics of different cultivated land types; (4) the core protected area was the prime cultivated land in the whole area and the primary goal of high standard basic farmland. The overall quality of the suitable transplanted areas was weaker than that of the core protected areas without obvious limiting factors, it could be improved by taking measures such as strengthening soil water and fertilizer conservation, establishing and perfecting irrigation facilities and making the suitable transplanted areas an object of basic farmland. The arable land in key renovation area had low overall quality with obstacles in all aspects, its management should be strengthened to improve the quality through land consolidation, and make this type of land as an alternative area for high standard basic farmland construction. As the inferior land of the whole area, the returning farmland should be returned to forest and grass while strengthening the improvement.
