Poyang Lake, the largest freshwater lake of China, serves as a crucial wintering site for migratory birds in East Asian–Australasian Flyway, where habitat quality is essential maintaining diverse bird populations. Recently, frequent alternation extreme wet years, e.g., 2020, and dry 2022, have inflicted considerable perturbation on local wetland ecology, severely impacting avian habitats. This study employed spatiotemporal fusion method (ESTARFM) to obtain continuous imagery Lake National Nature Reserve during seasons from 2020 2022. Habitat areas were identified based classification water depth constraints. The results indicate that both conditions exacerbated fragmentation shallow habitats showed minor short-term fluctuations response levels but more significantly affected by long-term hydrological trends. These exhibited interannual variability across different affecting their proportion within overall distribution area. demonstrates ability ESTARFM reveal dynamic changes responses conditions, highlighting critical role analysis. outcomes this improve understanding impact habitats, which may help expand knowledge about protection other floodplain wetlands around world.

The Panjin Wetland is a complex ecosystem comprising coastal and inland wetland. It has an important function in wetland conservation ecological. For this research, we quantified the landscape type changes from 1992–2022, analyzed interaction between combined PLUS InVEST models to predict future evolution of spatial temporal patterns habitat quality (HQ) Wetland. results showed following: (1) change natural area 1992 2022 generally decreasing trend, trend fragmentation. In 2032, ecological protection scenarios increase 79.51 km2 wetland, while other decrease. (2) 2022, average score 0.441, scores development scenarios, farmland economic are 0.427, 0.448, 0.438, 0.416, respectively. (3) outcomes study offer insights into sustainable management rational thereby contributing existing body knowledge field particularly areas land planning forecasting.
