Surface erosion rate is an important subject in evaluating geomorphic evolution of landforms. In-situ cosmogenic radionuclide ¹⁰Be was used to estimate the erosion rate in the southeastern Tibetan Plateau, where the precipitation is much higher than that in the central Tibetan Plateau. The determined erosion rates of <berType="1" TCSC="0">60 mm/ka (with a mean value of 27. 1±10. berType="1" TCSC="0">2 mm/ka) are comparable with the erosion rates in other mountainous regions. Compared with the erosion rates in the central Tibetan Plateau, the erosion rates in the southeastern Plateau are higher, which could be due to the difference in precipitation. Both tectonic uplift and climate (especially precipitation) affect the erosion of landforms in the southeastern Tibetan Plateau.
