ABSTRACT Crop rotation can help to alleviate land use pressure, prevent soil degradation, and promote sustainable agricultural development. Land in Northeast China has long been overused ensure national food security. Maize–soybean (MSR) is an effective conservation strategy, but its suitability not yet determined China. In this study, we applied optimized MaxEnt model by integrating multiple environmental variables systematically predict the of for maize soybean cultivation, establish MSR function, define specific range priority The obtained significantly improved performance, where suitable areas covered 60.25% 56.88%, respectively, total area Suitability was influenced factors, including climate, topography, soil, hydrology, conditions, particularly gravel content depth, were identified as main factors. Extensive are supporting MSR, highly only account 6.96% area, they primarily located Songnen Plain, most which developed into cropland. scientifically implementing thereby providing crucial support adjusting planting structure optimizing planning
