摘要
Urban areas are now highly interconnected with each other and with other landscapes through the global exchange of materials,resources,and people.These urban land teleconnections mean that the interrelationships between urbanization and land-cover change are no longer tightly linked in geographic space(Seto et al.2012).Actions at one or multiple urban centers can have concentrated or dispersed impacts on more distant landscapes;and these impacts are likely to increase over time.By 2030,Fragkias et al.(2013)predict that two thirds of the urban landscapes will have been built in the preceding 30 years.Accommodating the rise in human urban populations in the face of glob-al climate change without compromising ecosystem sustainability and resilience presents an enormous challenge.Finding solutions requires a concerted shift in our thinking,not the least of which is the frameworks we use to con-ceptualize an urban world.
