Abstract: Taking Bachu County of Xinjiang as the research area, the planting structure of major crops of wheat, corn and cotton in the county was refined by GIS and mathematical model integration technology. Under the constraint of “water-grain”conditions, the distribution of grain crop planting was comprehensively analyzed, aiming to provide scientific references for the planning, utilization, and optimal allocation of reserve cultivated land resources in the extremely arid areas of northwest China. The results showed that the planting suitability of corn, wheat and cotton was 0.856 4,0.708 4 and 0.706 5, respectively. The suitability for these three crops was relatively close, and the spatial distribution was characterized by high suitability in the central region. The results of single crop suitability zoning evaluation showed that cotton was mainly in grade II area, accounting for 40.11%, corn and wheat were mainly in grade III area, accounting for 63.50% and 64.12%, respectively. Under the constraint of “water-grain” conditions, the planting area of grain crops (wheat and corn) was 5 129.92 hm2, accounting for 35.98%. Among them, the planting area of Qiongkuerqiake Township was the largest, with an area of 1 463.21 hm2, accounting for 28.52%. The area of Aksak Majele Township in the central region was the second, which was 1 138.67 hm2, accounting for 22.20%.
