摘　　要：可达性是高校校园步行出行的基本要求.然而,我国高校新校区既有步行路网存在局部空间可达水平偏低、近距离绕行等问题.本研究以重庆医科大学缙云校区为例,采用空间句法理论下的线段模型和ArcGIS最优路径分析模型,量化其步行时空可达水平;结合步行空间实际使用水平,提出校园步行路网的改善方案并评估方案的步行可达性.研究发现:(1)分级的步行路网可提升全局和局部空间可达性,精细的道路设施设计可确保实际使用的可达性;(2)有序的游憩步道可增强空间感知的可达性;(3)以吸引点为导向的步行捷径可改善时间可达性.Accessibility is a fundamental requirement for walkingthrough the campus of university.However,new university campus face issues of pedestrian road networks,such as limited local spatial accessibility and short-distance detours.Taking Jinyun Campus of Chongqing Medical University as an example,this paper quantified the spatiotemporal walking accessibility using the line segment model under the space syntax theory and the ArcGIS optimal path analysis model.By combining the modeling results with real-world usage of the walking spaces,this paper proposed the improved plan for the pedestrian road network on the campus and evaluated its walking accessibility.The research findings indicate that:①The hierarchical pedestrian network can improve both global and local accessibility,and the fine design of road facilities can ensure the practical accessibility.②Incorporating orderly recreational trails improves the accessibility of spatial perception.③Creating destination-oriented pedestrian shortcuts enhances the temporal accessibility.
