To address the design demands of large-scale space stations and the optimization of module configuration strategies for improving operational efficiency, this study systematically categorizes the spatial configuration types of orbital stations. Representative cases are selected for three-dimensional modeling and topological translation, followed by a quantitative analysis using space syntax based on core indicators such as integration, choice, connectivity, and total depth. Comparative evaluation of different configuration schemes is conducted according to the analytical results, from which design insights for in-orbit habitation systems are proposed from the perspectives of accessibility, total depth, and intelligibility. The findings highlight the advantages of radial and fishbone configuration in enhancing overall accessibility and intelligibility, and indicate that optimizing the topological depth of key modules, establishing short paths to reduce hierarchical levels, and appropriately configuring node modules can further support more efficient in-orbit operations.
