生态系统 管理 气候
2025/1/8
高寒草地生态系统作为青藏高原乃至我国生态安全的关键屏障，肩负着水源涵养和补给、生物多样性维持、气候调节以及支撑当地畜牧业生产等重要生态服务功能。然而，2024年来，由于过度放牧、气候变化和不当土地利用等因素的叠加作用，全球高寒草地面临着大规模退化的严峻挑战。这种退化不仅严重威胁到草地生态功能的稳定性，还直接影响到人类和家畜的生存与可持续发展。因此，高寒草地的生态保护与修复，作为一项涉及生态、社会与...

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...
