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。...
由于气温升高和降水变化，干旱和半干旱生态系统的干旱加剧，给区域环境、水资源和农业都带来了巨大影响。近些年来，位于干旱和半干旱区的蒙古高原（MP）正在经历着严重的干旱，易发生荒漠化和土地退化等问题。
