Coastal Wetlands in the Changjiang Estuary

摘要: The enormous quantities of sediment produced by the Changjiang (Yangtze River) have created extensive coastal wetlands in estuarine region, which been colonized various types salt marsh vegetation. As Estuary is located adjacent to megacity Shanghai, human activities exert substantial pressures on and cause ecosystem degeneration consequent decreases or loss services. major stresses from include urbanization, reclamation, introduction invasive species, overfishing, environmental pollution. In this chapter, succession plant communities described. spatial temporal variation marshes are analyzed basis remote sensing (RS) mapping, combined with field inventories sampling plots. population expansion an exotic Spartina alterniflora, after its 1990s, described analyzed. impacts invasion S. alterniflara benthic examined along intertidal gradients, history A cellular automaton (CA) model was developed simulate alterniflora study interactions between pattern vegetation ecosystems. Field experiments a demonstration project were carried out control alterniflora. Finally, chapter discusses future development, management, conservation biodiversity Estuary.
