Overview

Time series remote sensing analysis reveals native saltmarsh loss from reclamation and plant invasion in the Yangtze River estuary, highlighting distinct drivers across plant communities.

Key Points

  • Reclamation eliminated 503.93 km2 of native saltmarsh vegetation, while Spartina alterniflora invasion caused an additional loss of 78.96 km2 in the Yangtze River estuary.
  • Assessment using multi-source time series remote sensing data combined an object-based phenology algorithm with random forest algorithm to map annual saltmarsh vegetation dynamics.
  • Findings highlight that reclamation intensity governed Phragmites australis spread, while interspecific competition with Spartina alterniflora determined Scirpus communities.
