都市再生中的废弃铁路改造——中东铁路公园建设20年影响分析

Revitalization of Abandoned Railways in Urban Regeneration—A Twenty-Year Impact Assessment of the Chinese Eastern Railway Park

摘要: 研究采用多源数据融合分析方法，整合遥感影像解译(1990~2020年Landsat系列)、空间句法建模(Depthmap10.8)、POI核密度分析及问卷调查(N = 412份)四维数据，构建“空间形态–功能演化–社会感知”综合评价体系。研究发现：中东铁路公园改造后，以公园为中心800米半径范围内的步行可达性提升37.2% (R² = 0.81)，商业用地溢价率达到182% (相较于3公里外对照区)，但居民对工业遗产认知度存在代际差异(60岁以上群体认知度达89.3%，20~30岁群体仅31.7%)。通过构建多元回归模型验证，道路整合度每提升1个单位，商业POI密度增加0.87个/km² (P < 0.01)。研究创新性提出“遗产廊道活化度”评估指标，为后工业景观更新提供量化决策工具。

Abstract: This study employs a multi-source data fusion methodology, integrating four dimensions: remote sensing imagery interpretation (Landsat series, 1990~2020), spatial syntax modeling (Depthmap 10.8), point-of-interest (POI) kernel density analysis, and questionnaire surveys (N = 412). A comprehensive evaluation framework encompassing “spatial morphology, functional evolution, and social perception” is constructed. The findings reveal that following the redevelopment of the China Eastern Railway Park, walkability within an 800-meter radius improved by 37.2% (R² = 0.81), and commercial land value premiums reached 182% compared to a control zone located 3 kilometers away. Nevertheless, generational disparities were observed in public awareness of industrial heritage, with 89.3% recognition among individuals aged 60 and above, contrasted with only 31.7% among those aged 20~30. A multiple regression model further verifies that for every one-unit increase in street integration, commercial POI density rises by 0.87 POIs per square kilometer (P < 0.01). The study innovatively proposes the “Heritage Corridor Activation Index” as a quantitative tool to support decision-making processes in post-industrial landscape revitalization.
