沈镭 李德龙 植被响应 干旱时间 尺度 演变 气候
2024/2/26
干旱是造成植被死亡的主要驱动因素之一。在未来气候变化下干旱的强度、持续时间和频率会进一步增加，从而导致更高的森林死亡。目前的植被-干旱耦合研究很大程度上被忽视了植被响应干旱的最佳时间尺度（反映植被对干旱敏感性的一个关键指标），要么考虑了干旱时间尺度但忽略了干旱尺度的时间演变趋势，或考虑了植被-干旱敏感性的时间演变趋势而未能考虑干旱时间尺度的影响。在考虑到过去三十年植被对干旱的最佳响应时间后，植被对...
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。

大气CO2浓度升高不仅加剧了全球气候变化，还改变了动植物的生长发育过程。其中，对C3植物最重要的影响是增加了光合作用，并降低气孔导度。而植物气孔导度的降低导致植物蒸腾作用降低，水分利用率增加，对蚜虫这类取食植物韧皮部汁液的刺吸式口器昆虫来说，寄主植物保持相对高的水势和膨压对蚜虫被动取食、获取植物汁液非常重要。在调节水分利用效率和叶片气孔的张开程度过程中，植物脱落酸（ABA）信号途径发挥至关重要的作...
