摘      要：There is an abundance of conceptual frameworks relevant to sustainability in urban ***,to advance urban ecological science and its application to sustainable urban transformations,key existing frameworks must be *** paper is a conceptual synthesis cast in essay form in order to encompass a broad range of relevant *** starts from the premise that the familiar models of metropolitan and megalopolitan urban structure,of industrially driven urban development,and of the contrasts between urban and non-urban lands are manifestly inadequate representations of evolving global *** inadequacy is illustrated with examples from the United States and from *** the form and the interactions involved in contemporary urbanization and urban change suggest the need for a new integrated framework synthesizing two existing yet still evolving concepts:(1)The urban megaregion framework accommodates the spatial extent,interdigitation of contrasting land uses,and the linked spatial relations between nominally urban and nominally rural areas.(2)The new concept of the continuum of urbanity emphasizes the shifts in livelihood and lifestyle driven by regional and global teleconnections and their joint effects on local environments and *** these frameworks suggest a common conceptual structure for addressing urban areas of different ages,sizes,forms,and dynamics in both urbanizing and urbanized areas in developing and developed countries and *** synthesis of frameworks points to empirical research needs,and has the potential to better match sustainability plans and actions with the diverse urban forms and dynamics now appearing around the world.
