Renovation and Renewal for Existing Dedicated Rail Lines in Dalian
The renovation and renewal of existing dedicated rail lines in cities have been generally frag-mented,without fully achieving their spatial value and social significance.Conducting a systematic study on these rail lines as a whole will significantly enhance their social,economic,and environmental benefits.This paper outlines the current usage state and poor environmental quality of Dalian's existing dedicated rail lines.It reveals the environmental characteristics and disparities of these rail lines in different locations from three perspectives:the type of land use and development intensity within the railway impact area,the spatial relationship between the existing rail lines and urban roads,and the population density and aging de-gree within the railway impact area.Based on domestic and international experiences,the paper summariz-es five primary types of renovation and renewal for the existing dedicated rail lines and their adaptability to environmental characteristics.The existing rail lines in Dalian are categorized into 13 sections,and the renovation and renewal strategies for each section are proposed from the perspectives of functional trans-formation,spatial restructuring,and implementation and operations to promote urban renewal and spatial quality enhancement.
