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...

2010/8/13
The emission of organic aerosols (OA) in the ambient air by residential wood burning is nowadays a subject of great scientific concern and a growing number of studies aim at apportioning the influence...
Measured and predicted aerosol light scattering enhancement factors at the high alpine site Jungfraujoch
aerosol light enhancement factors high alpine site Jungfraujoch
2010/3/16
Ambient relative humidity (RH) determines the water content of atmospheric aerosol particles and thus has an important influence on the amount of visible light scattered by particles. The RH dependenc...
