However, evaluating the precise alignment between infrastructural topology and cultural meaning remains a methodological challenge. To move beyond macro-level assumptions, this study constructs a novel \u201cspatial\u2013semantic coupling\u201d diagnostic framework. Integrating multi-source street-view data, Space Syntax, and the zero-shot semantic extraction capabilities of the CLIP model, we performed high-resolution visual semantic identification across 550 fine-grained sampling points in the 6.6 km2 South Central Axis Core Area. Rather than merely observing a general \u201cdecoupling,\u201d our diagnostic tool successfully mapped the complex spectrum of spatial alignments. While it accurately diagnosed areas with \u201cidle spatial potential\u201d\u2014where high Global Integration (Mean = 0.924) fails to translate into Visual Attraction (r = \u22120.03) or Historical Perception (r = 0.01)\u2014it also precisely identified \u201cSynergistic\u201d heritage cores and \u201chidden gems\u201d within capillary hutongs. Furthermore, the framework diagnosed a severe \u201cgreen island\u201d effect (Mean = 0.26) and a structural contradiction between Spaciousness and Historical Perception (r = \u22120.33). By utilizing Bivariate LISA to geographically pinpoint these varying coupling characteristics (e.g., severe \u201cHigh\u2013Low\u201d spatial frictions at gateway transportation hubs), this study establishes a highly scalable, data-driven analytical paradigm for targeted micro-renewal, ensuring the precise alignment of physical centrality and cultural perception in complex historic districts globally.<\/jats:p>","DOI":"10.3390\/ijgi15050203","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T19:35:43Z","timestamp":1778528143000},"page":"203","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Measuring Spatial\u2013Semantic Coupling in Historic Districts Using Space Syntax and the CLIP Model: A Case Study of the South Central Axis Core Area in Beijing"],"prefix":"10.3390","volume":"15","author":[{"given":"Qin","family":"Li","sequence":"first","affiliation":[{"name":"School of Architecture and Urban Planning, Beijing University of Civil Engineering and Architecture, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-5001-2598","authenticated-orcid":false,"given":"Zhenze","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Architecture and Urban Planning, Beijing University of Civil Engineering and Architecture, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingping","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Architecture and Urban Planning, Beijing University of Civil Engineering and Architecture, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3072-2042","authenticated-orcid":false,"given":"Wenlong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Urban Economics and Management, Beijing University of Civil Engineering and Architecture, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3917-250X","authenticated-orcid":false,"given":"Yijun","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Educational Science, Shaanxi Xueqian Normal University, Xi\u2019an 710061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lixin","family":"Jia","sequence":"additional","affiliation":[{"name":"School of Physical Education, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,7]]},"reference":[{"key":"ref_1","first-page":"62","article-title":"Space Syntax\u2014New Perspectives on Cities","volume":"1","author":"Hillier","year":"1985","journal-title":"New Archit."},{"key":"ref_2","first-page":"62","article-title":"Improvement of Spatial Unit Segmentation Method of Space Syntax Axial Map in the Application of Grid Road Network Cities","volume":"25","author":"Shao","year":"2010","journal-title":"Int.
