“…Coastal wetlands are located in coastal zones and link terrestrial and marine ecosystems (Guo and Zhang, 2019), and they are strongly affected by human activities. Rapid land use change in coastal zones, such as urbanization, reclamation and dredging projects, represents an important cause of coastal wetland degradation (Fang et al, 2015;Guo and Zhang, 2019;Schleupner, 2008). With powerful ecological service functions, such as storm buffering, sheries production, and water quality enhancement (Barbier, 2013), coastal wetlands can support abundant biodiversity and provide the foundation for regional development (Ma et al, 2014).…”
