Abstract

This study analyzes the Dongting Lake's spatiotemporal changes using long-term remote sensing data. The key findings include: (1) From 2005 to 2015, the lake's water area decreased by 61.12% during the wet season and increased by 50.38% in the arid season. (2) The centroid migration was most significant from 2005 to 2010 (8565.82 meters) due to water area fluctuations but decreased to 0.95 meters from 2010 to 2015. (3) Climate factors, particularly precipitation, had a moderate correlation with area changes (0.20 in the wet season, 0.31 in the dry season). The study also explores the impact of human activities on water area changes, providing valuable insights for sustainable development strategies.
