Abstract The large-scale expansion of cultivated land in the arid region has caused water overload and frequent ecological problems, so it is urgent to reduce the area of cultivated land to save irrigation water. Therefore, exploring the spatial optimized scheme of ecological cropland conversion under the constraints of water resources can not only contribute to resolving the current ecological problem of arid areas, but also help implement land use planning and decision-making. Until now, the research on quantitative analyses of the multi-benefit contradiction of the cropland-conversion plan is still insufficient. Therefore, a spatial optimization allocation and trade-off analysis model for ecological cropland conversion is built in this study. Taking Qitai County as a case study, we built a solution group of ecological cropland conversion under the constraint of water resources. Two scenarios, priority for maintaining cultivated land scale and priority for ecological environment, were designed in this research to realize the spatial simulation and optimization of ecological cropland conversion by Ant Colony Optimization Algorithm. Results show that the cultivated land area of Qitai County is 99.39 thousand hectares in priority for maintaining cultivated land scale scenario, and 69.55 thousand hectares in priority for ecological environment scenario. In the cropland-conversion process, the proportion of ecological water consumption in the river channel accounted for 10% of the total water consumption in the cultivated land retain priority scenario and 30% in the ecological protection scenario; and the amount of windbreak and sand fixation increased from 7.13 million tons to 8.17 million tons, while the economic benefit decreased from 3.49 billion yuan to 2.48 billion yuan. Through comparing the reduction of unit economic benefit producing the increasing proportion of unit ecological benefit, the scenario that cultivated land area decreased to 83.49 thousand hectares was chosen as the optimal one considering the trade-off between economic and ecological benefit. The cropland-conversion areas were mainly located in the northeast, northwest and southwest edges of the farmland concentration area in Qitai County, which will benefit the prevention and control of desertification in the north and the protection of water resources in the south. This research realizes the spatial simulation and optimization of the ecological-conversion plan under the constraints of water resources in arid areas, which provide significant reference to agricultural management and ecological protection.
