REPRODUCTION OF MARGINALIZED SPACE:DISSIPATION MECHANISM AND CAPTURE PATH OF ECOLOGICAL VALUES IN URBAN FRINGE AREAS
Rapid urbanization is often accompanied by ecological degradation and value dissipation in urban fringe areas(UFAs).The consequent weakening of comparative location advantages has restrained the potential of capital accumulation and value generation in the UFAs,leading to the development dilemmas of sluggish urban regeneration progress and inefficient urban expansion.Through a retrospective review of ecological capitalization process in the UFAs,this paper develops an explanatory framework for the spatial representation and cognitive limitations of ecological value dissipation,and proposes corresponding spatial planning strategies for the capture of ecological values in the UFAs.The paper concludes that:(1)the ecological value dissipation in the UFAs triggers the substitution of spatial elements,impedes land regeneration processes,and leads to the diffusion of ecological costs at multiple scales;(2)the deviation of value accounting,the dilemma of decoupled growth,and the paradox of ecological regulation are key factors restricting the cognition of ecological values in the UFAs;(3)in planning practice,the spatial reproduction of the UFAs can be promoted through coordinated resource allocation in time and space,value creation based on the integration of urban and green spaces,and system maintenance featuring protection-development complementation.
