Abstract: 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 (
