Abstract: The coastal wetlands in Shenzhen Bay are internationally important habitats for waterbirds. They are also areas with rapid economic development and land use change. However, intensive building and construction greatly affect waterbirds’ flight processes. This study focused on waterbirds’ flight resistance pattern and spatial management strategies by using minimum cumulative resistance (MCR) model and waterbirds’ foraging flight and avoidance behavior. Little Egret (Egretta garzetta) and Shoveler （Anas clypeata) were selected as indicator species, and resistance surfaces were established to simulate these two species’ horizontal movement across urban regions. Results revealed how urban lands and buildings influence waterbirds’ flight processes. In addition, a comprehensive flight resistance pattern was built by overlaying the resistance surfaces of the two indicator species, with low, medium and high resistance levels. Finally, relative management strategies were proposed to protect the flight processes of waterbirds. This study illustrated that the relationship between urbanizing areas and biological processes has a vital practical significance on sustainable development of city.
