Mapping typical salt-marsh species in the Yellow River Delta wetland supported by temporal-spatial-spectral multidimensional features.

The native salt marsh plants of the Yellow River Delta wetland such as Suaeda salsa and Phragmites australis, providing significant habitats for rare waterfowl, are the key to conserve biodiversity and enhance habitats of this critical wetland. These plants are undergoing severe degradation due to rapid invasion of Spartina alterniflora, which has been a major growing threat to the livelihood of waterfowl and the sustainability of the Yellow River Delta wetland. Monitoring the spatial pattern of salt marsh species is fundamental to the conservation and restoration of the ecological functions in the Yellow River Delta wetland.

Parameterizing the Yellow River Delta tidal creek morphology using automated extraction from remote sensing images.

The tidal creek is an important part of the intertidal zone, which maintains the balance between depositional processes and a given hydrodynamic environment. Much can be inferred about the development and evolution of a tidal creek by examining its morphometry characteristics; this information can also provide scientific decision support for the development and utilization of coastal tidal flats. In this study, we propose a complete system of large-scale tidal creek morphometry characteristic extraction algorithms.
