Lancang River (LCR), the upper region of large transboundary Mekong River, provides a critical understanding terrestrial weathering status and CO2 consumption. Riverine Sr isotopes play crucial role in identifying link between continental nearby ocean. This study reported spatial variations data from LCR during flood season, were coupled with hydrochemical based on Bayesian model to assess solute sources. Results showed that carbonate was predominant contributor riverine dissolved (contribution ratio ∼35%). Besides, halite dissolution, silicate weathering, groundwater contributed 28, 16, 12% Sr, respectively. The chemical rate relatively high, level consumption doubled within decade, indicating potential regional climate change. Flux estimations revealed 42.9 tons 87Sr introduced annually, eventually reaching Pacific Ocean. Silicate-derived accounted for 38% this flux, exerting significant influence seawater Sr-isotopic composition. Dam construction warming accelerated snow melting (headwater area) increased precipitation may enhance suitability weathering. A more systematic controlling factors is needed provide better insight into basin management Lancang-Mekong region.
