High-resolution satellite imagery providing long-term, continuous information on surface water extent in highly developed regions is paramount for elucidating the spatiotemporal dynamics of bodies. The landscape bodies a key indicator quality and ecological services. In this study, we analyzed dynamics, including rivers, lakes, reservoirs, using Landsat images spanning from 1980s to 2020, with focus Coastal Chinese Mainland (CCM) region. Our objectives were investigate temporal spatial variations area characteristics, explore driving forces behind these variations, gain insights into complex interactions between evolving environmental conditions, ultimately support sustainable development coastal regions. findings revealed that reservoirs constitute largest proportion water, while lakes occupy smallest share. Notably, trend expansion CCM was observed, mainly construction new reservoirs. These primarily gained areas agricultural land river floodplains early stages (1980s–2000), greater encroached upon by later periods (2001–2020). At level, tendency toward fragmentation complexity particularly evident. Human interference, urbanization, played pivotal role surfaces. While reservoir benefits resource assurance, flood control, prevention, it also poses eco-hydrological challenges, deterioration, reduced hydrological connectivity, aquatic ecosystem degradation. study provide essential data development. underscore urgency importance integrated management strategies, efforts aimed at conservation restoration natural scientific regulation artificial Balancing human needs preservation integrity crucial facilitating strategy integrates climatic socio-economic dimensions, ensuring use protection future generations.
