| 英文摘要 | The Dogai Coring Lake on the Tibetan Plateau, with widespread permafrost and glaciers in the watershed, has expanded rapidly between 2014 and 2020. However, it remains unclear how much melting water from permafrost and glaciers contributes to the increase in lake volume. This study quantifies the potential amount of water released by the melt of permafrost and glaciers, and assesses the fraction of water storage gains in the lake offset by the loss from the cryosphere (i.e., ground ice and glaciers). The small baseline subset interferometric synthetic aperture radar (SBAS-InSAR) method was used to derive the spatiotemporal changes in surface deformation, which then assisted the estimation of the potential water release from ground ice melting. The glacier mass balance was estimated using a geodetic method with ASTER DEMs. Results show that 51.3 % of the region experienced subsidence with rates in the range of 5-20 mm center dot a(-1) during 2014-2020. Ground ice melting released water at a rate of 35.1 x 10(6) m(3)center dot a(-1), accounting for similar to 19.3 % of the increase in lake volume. The glacier mass loss rate was estimated to be - 0.69 +/- 0.04 m w.e. yr(-1) (113.6 +/- 7.3 x 10(6) m(3)center dot a(-1)), contributing similar to 62.5 % to the lake volume increase. Our results show that the water storage loss in the cryosphere has largely (similar to 80 %) offset the water storage gain in the lake, suggesting that cryospheric meltwater is an important factor regulating water budget change of the lake watershed. |
