The distribution of coastal wetland vegetation is influenced by biological invasions, human reclamations and climate changes, which continually reshape structures. However, limited attention has been given to the impact invasion on native tidal wetlands. This study focuses wetlands Chongming Island, employing a multi-feature dataset combining spectral, phenological, temporal information Google Earth Engine (GEE) platform. Using Random Forest (RF) classification method, we analyzed annual changes examined distinct effects natural anthropogenic factors. research results indicate that: (1) From 1985 2019, total area Island expanded, while decreased due embankment construction island connection projects. (2) dropped its lowest point in 2002 (3812.76 ha), then gradually recovered. (3) Human reclamation was primary driver from 1995. (4) Vegetation Dongtan both factors, whereas Beiliuyao affected expansion S. alterniflor. These findings provide valuable insights into drivers long-term offering essential data theoretical support for sustainable development management Island's ecosystems.
