Climate warming can cause intense changes in regional soil freeze/thaw dynamics and thus exerts strong effects on hydrological processes. Because permafrost conditions vary widely across the Tibetan Plateau (TP), a better understanding the potential influences of permafrost types is helpful to project future hydrological changes. Using multilayer soil temperatures from 45 meteorological stations, this study investigated regional near‐surface soil warming on the TP (1981–2015) and related hydrological implications in two typical alpine basins. In cold and warm seasons, near‐surface soil temperature gradient (0–5 cm) showed significant increasing trends with average rates of 0.31 ± 0.13 and 0.19 ± 0.08°C per decade (p 60%) basin, but had much weaker hydrological effects in the low‐permafrost (

近地表土壤变暖对青藏高原的水文影响

气候变暖会导致区域土壤冻融动态发生剧烈变化，从而对水文过程产生强烈影响。由于青藏高原 (TP) 的永久冻土条件差异很大，因此更好地了解永久冻土类型的潜在影响有助于预测未来的水文变化。本研究利用来自 45 个气象站的多层土壤温度，调查了青藏高原地区近地表土壤变暖（1981-2015 年）以及两个典型高寒盆地的相关水文影响。在寒冷和温暖季节，近地表土壤温度梯度（0-5 cm）显示出显着增加的趋势，平均速率为 0.31 ± 0.13 和 0.19 ± 0.08°C 每十年 (p 60%) 流域，但水文效应要弱得多在低冻土层（
