Temporal and Spatial Dynamics of Surface Water Temperature Changes in China's Major Lakes

Water Resources Research, Volume 61, Issue 7, July 2025.
Abstract Globally the lake surface water temperature (LSWT) has shown an upward trend and exhibits significant spatial heterogeneity, but previous studies have indeed delved it under current period. Here, we investigated the characteristics of LSWT variation in major lakes of China over two centuries.
