西藏高山草原的洪涝增加了土壤碳含量,但增加了受气候驱动的碳损失影响的脆弱性。 Waterlogging in Tibetan alpine meadows boosts soil carbon but increases vulnerability to climate-driven carbon loss.

中国科学家发现,青海-西藏高原高山草原的水浸积会增加土壤和地下的微生物死体碳,微生物碳在水文梯度上占土壤有机碳总量的32%. Chinese scientists have found that waterlogging in alpine meadows on the Qinghai-Tibet Plateau increases microbial necromass carbon in both topsoil and subsoil, with microbial carbon making up about 32% of total soil organic carbon across a hydrological gradient. 虽然洪涝会推动土壤碳总储存,但它也会增加不稳定的碳成分,增加未来气候变暖和湿地退化造成的碳损失风险。 While waterlogging boosts overall soil carbon storage, it also raises unstable carbon components, increasing the risk of carbon loss due to future climate warming and wetland degradation. 这项研究以27个采样点为基础,在Catena发表,对该区域的碳动态和气候抗御能力提供了重要的见解。 The study, based on 27 sampling sites and published in Catena, offers key insights into the region’s carbon dynamics and climate resilience.
