The Planning Practice Study of Urban Green Space System in High-Density Urban Areas Based on the Concept of Ecological Restoration and Urban Repairing

摘要

Accompanied by China's New Normal Economy and Chinese social and economic transition. The urbanization has entered a new stage of improving quality and increasing efficiency as the main development, meaning that future urban construction shall not only focus on newly increased lands only, but also focus on better utilizing the existing resources of built-up areas and effective utilization of such resources. Urban railway lines, with traditional freight transport as the main function, are important existing resources. They used to make tremendous contributions to the industrial development of cities. However, they have gradually declined with upgraded industries in various cities. In addition, restrained by resources and environment, the network in the planning is difficult to implement in reality for the greenspace systems in high-density urban areas. As a result, how to better utilize existing resources and rebuild greenspace networks, cope with multi-component space demands with finite space resources have been an important issue for the ecological restoration and urban repairing of high-density urban areas. Based on this, typical high-density urban areas were taken as the research object with fully excavate the spatial potential of existing resources represented by abandoned railways, combine the network design of urban green space systems with important linear spatial elements and features, apply the planning strategies of "greening railways and linking river", "revitalizing railways and connecting urban areas" and "inheriting railways and boosting industries", and explore the important values of existing resources by reconstructing and perfecting the green space system in high density area. So as to sew up the wound of urban human ecological environment, link the patterns of urban economic ecological, and establish the new structure of ecology in high-density urban areas with a systematic manner.
