国外城市废弃线性高架空间的再利用

随着城市的重心转移、交通多元化等一系列快速发展,城市中很多高架铁路、高架公路遭到废弃,这严重影响了城市的交通、治安和环境。通过对城市废弃线性高架空间更新的时代背景和生态特征进行分析,探寻其在建设中的问题与挑战,提出生态恢复的手段,利用自我恢复能力,辅以人工措施,形成稳定的生态系统。结合国外经典案例,从空间营造、社会功能发挥、生态恢复3大方面对城市的线性空间进行更新,修复"疮疤",形成健康肌理,重新融入城市景观建设中。

Reuse of Abandoned Linear Space of Urban Viaduct in Foreign Countries

Along with the rapid urban development such as the shifting heart of city, diversified transportation means, a great number of urban elevated railway and viaducts were abandoned consequently, which has seriously affected transportation, security and environment in cities. Through the analysis on the background and ecological characteristics of upgrading the abandoned linear elevated urban space, the paper explored the issues and challenges arising in urban construction, and proposed to adopt the ecological restoration means and make use of self-rehabilitation ability, which is complemented by artificial measures, to form a stable ecosystem. Based on the classic cases in other countries, the linear urban spaces have been updated and restored by spatial creation, social functioning and ecological restoration, with the aim at reshaping healthy texture for reintegration into city's landscape construction.
