植被物候是生态系统响应气候变化的敏感指标。在全球气候变化背景下，植被物候变化会影响生态系统碳循环及水热平衡过程。作为世界上海拔最高的高原，寒冷干旱的青藏高原植被物候是受温度还是水分主导仍然存在争议。青藏高原有大面积的沼泽湿地分布，沼泽相对充裕的水分条件为进一步揭示这一问题提供了理想的条件。明确青藏高原沼泽植被物候时空变化及对气候变化响应机制，能为预测区域碳循环、揭示植被与气候变化关系提供科学依据。...
了解物种的种群趋势和分布范围动态对于全球物种保护至关重要。自人类世以来，随着人类活动强度的持续升级，全球物种遭受了栖息地的急剧丧失和分布范围的缩小。由于大部分原栖息地因人类活动出现各种方式的退化，动物会迁移到新的栖息地以获得更大的生存机会。这种动态的种群分布范围对于物种的生存至关重要，与种群灭绝的概率直接相关。因此，了解种群分布动态变化的机制并识别驱动因素对于预测和指导种群的保护至关重要。
