A critical function of animal movement is to maximize access essential resources in temporally fluctuating and spatially heterogeneous environments. Seasonally mediated resource fluctuations may influence movements, enabling them track changing distributions, resulting annual migration patterns. The conservation-dependent giant panda ( Ailuropoda melanoleuca) displays seasonal patterns; however, the key factor driving these patterns remains poorly understood. Here, we used GPS tracking collars monitor movements six pandas over a 12-year period across different elevations, performed statistical analysis directions, routes, habitat revisitation, home range overlap, first arrival events, stability. Our results revealed compelling pattern migrations that facilitated ability forage at appropriate time place nutritional intake. indicated utilize spatial memory locate reliable food resources, as evidenced by their return same or similar winter summer ranges consistently maintained percentage overlap. These novel insights into foraging ecology not only enhance our understanding its adapt nutritionally poor dietary but also provide important information for development utilization-based protection management strategies.动物运动的一个关键功能是在时间波动和空间异质性的环境中最大限度地获得关键资源。季节性的资源波动可能影响动物的运动，导致它们跟踪不断变化的资源分布，产生年度迁移模式。保护依赖的大熊猫( 表现出季节性迁移模式，然而塑造这些季节性迁移模式的关键因素仍然不为人知。在该研究中，我们使用GPS跟踪项圈监测了6只大熊猫在12年期间不同海拔高度的运动情况，对其季节性迁移方向、路线、栖息地重访、巢域重叠、首次到达事件进行了统计分析，并检验了他们的稳定性。我们的研究结果揭示了一个令人信服的季节性迁移模式，该模式有助于大熊猫在适当的时间和地点获得食物资源，以最大限度增加营养摄入。我们的研究结果表明，大熊猫利用空间记忆来定位可靠的食物资源，它们每年都会返回相同或相似的冬季和夏季巢域范围，并且巢域范围重叠率始终保持不变。这些对大熊猫觅食和运动生态学的新见解增强了对大熊猫适应营养不良食物资源的理解，并为受空间和资源利用模式影响的保护和管理策略提供了重要参考。.
