Study on the Ecological Restoration of the Urban Remnant Patches in the Process of Rapid Urbanization

Abstract

The rapid urbanization led to a large number of remnant plaques. It plays an important role to restore the urban residual plaques for the resolution of contradiction between resource demand and limited environmental carrying capacity and the series of problems of urban construction such as increasing environment, urban image, urban vitality and economic development, etc. Based on the study of time and content, urban wildlife habitat and biodiversity conservation, basic theory and practices of urban sustainability and ecological design standards, the progress of ecological restoration of patch was discussed in domestic urban areas. The foreign dynamic progress was also discussed from four aspects of content: practice of patch, patch fragmentation and disturbance, comprehensive ecological service function, sociology of restoration of public participation, etc. The existing problems of the study were analyzed, which included insufficient understanding, limitations of research content, lack of systematic theory and technical guidance, research deficiency of the key factor of human. And the connotation and denotation were defined. A system method of urban ecological restoration was put forward: a method of Artificial Ecological System, as an artificial ecological system based on artificial positive interference on urban residual plaque, which is a positive response to the rapid rebalance and sustainable development of urban ecosystem, the artificial ecological system.
