城市地铁沿线地下空间开发价值评估体系探讨

Discussion on the Evaluation System for Underground Space Development Value along Urban Metro Lines

摘要: 城市地下空间是城市集约发展的关键战略资源，对破解城市土地资源土地瓶颈、提升空间利用效能具有重要意义。城市地铁建设有助于推动地下空间一体化开发，地铁沿线已成为城市地下空间高质量利用的重点区域。鉴于地下空间开发具有不可逆、高风险、高投入的工程属性，盲目开发易造成资源浪费与安全隐患，急需建立科学的价值评估体系。本文以工程实践为基础，构建质量与需求双维度评估模型，划定开发分级区域，为地铁沿线地下空间系统化、集约化、可持续开发提供前提支撑。

Abstract: Urban underground space is a key strategic resource for intensive urban development, which is of great significance to breaking the bottleneck of urban land resources and improving the efficiency of space utilization. The construction of urban metro helps promote the integrated development of underground space, and the area along the metro has become a key area for the high-quality utilization of urban underground space. Given the irreversible, high-risk and high-investment engineering attributes of underground space development, blind development is likely to cause resource waste and potential safety hazards, so it is urgent to establish a scientific value evaluation system. Based on engineering practice, this paper constructs a dual-dimensional evaluation model of quality and demand, delineates graded development areas, and provides a prerequisite support for the systematic, intensive and sustainable development of underground space along metro lines.
