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...
Thermal Remote Sensing for Global Volcano Monitoring: Experiences From the MIROVA System

Traditional agroforestry systems across South Asia have historically supported millions of smallholding farmers. Since, 2007 agroforestry has received attention in global climate discussions for its c...
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。...
