Health Assessment of Historic Blocks Based on Multi-Source Data: A Case Study of the Blocks Along Ciqi Street, Yongqing Street, and Yongtai Street in Shedian Town, Nanyang City, China

Year: 2025

Type: article

Abstract: In the context of building healthy cities and enhancing the quality of historic blocks, assessing their health levels is of critical importance. However, research on health assessments of historic blocks remains limited, and existing evaluation frameworks often struggle to balance comprehensiveness with contextual specificity. Using the blocks along Ciqi Street, Yongqing Street, and Yongtai Street in Shedian Town, Nanyang City, as a case study, this study develops a health assessment system comprising five primary indicators, including block safety, block comfort, block ecological nature, block convenience, and block cultural nature, along with eleven secondary indicators and seventeen tertiary indicators. Based on SHP data, street view imagery, meteorological data, DSM data, and other relevant datasets and employing multiple analytical methods, including ArcGIS, semantic segmentation, and Grasshopper, a health assessment of the target blocks is conducted. The results indicate that the target blocks face significant safety issues, with health challenges primarily associated with their internal built environments. Finally, the study proposes three measures for quality improvement, providing references for related research and the renewal of historic blocks.
