%X Based on ICESat-2 LiDAR altimeter data and empirical equations derived from self affine theory, the volume of lakes with an area greater than 0.01 km ² on the Qinghai Tibet Plateau in 2022 was estimated. The study found that the simulated lake volume matched well with the measured values on site, with an average absolute percentage error of 8.0% for the maximum lake depth and 19.7% for the lake volume. It is estimated that the total water storage capacity of lakes with an area greater than 0.01 km ² on the Qinghai Tibet Plateau in 2022 will be 1043.69 ± 341.31 km ³, of which about 70% (~734.8 km ³) of the lake water storage capacity is concentrated in the inner plateau (Qiangtang Plateau). This data, based on remote sensing methods, has preliminarily clarified the water storage capacity of lakes on the Qinghai Tibet Plateau, providing important data support for predicting future changes in lake water volume, analyzing hydrological balance, and managing water resources.
