英文摘要	The stability of the arable ecosystem plays a crucial role in the sustainable utilization of land resources and the efficiency of agricultural production. However, irrigated agriculture has led to severe desertification and salinization in arid and semi-arid areas, resulting in long-term low ecological stability of arable land. This study focuses on the arable ecosystem stability (AES) in the Hexi Corridor and constructs an AES evaluation model based on the pressure-buffer-response process. Using methods such as the revised wind erosion equation, remote sensing ecological index and path analysis to explore the spatiotemporal dynamics and driving mechanism of AES during the growing season (April-October). The results showed that the AES in the area was transitioning from a critical to stable state, with vulnerable arable land gradually decreasing while stable land increased. Stable arable land was concentrated in the middle reaches of the Heihe River basin, while arable land in the Shule River Basin was basically at critical level, a crucial area for wind erosion prevention. In the lower reaches of the Shiyang River Basin, much arable land was vulnerable to salinization, requiring urgent treatment. Complex climatic conditions and irrational irrigation patterns are the main causes of AES fluctuations. Agricultural engineering construction and favorable policy implementation can significantly improve AES. In addition, seasonal variability in wind erosion, salinization and AES was significant, with the worst in spring and the best in summer. Climate and vegetation factors have become the main factors affecting wind erosion and salinization. The fallow period before spring is a critical time for wind erosion control and salinity soil improvement. This study aims to provide theoretical guidance for the construction of agricultural production and ecological management in arid and semi-arid areas.
