本期为大家推介的内容为论文《中国城市活力中心的街道步行环境指数测度》(Measurment of Street Walking Environment Index for Urban Vitality Centers in Chinese Cities)，发表在《南方建筑》，欢迎大家学习与交流。
已有可步行性研究大多关注引发步行行为的建成环境特征，而对影响步行体验的街道环境探讨较少。以城市空间为视角，提出基于过街设施、街道绿化、沿街建筑宽高比、街道家具、机非隔离、步道宽度、占道停车、道路失修和专用自行车道等 9 项评价指标的步行环境评价方法。在中国 50 个典型城市的 71 个城市活力中心内，结合街景影像与虚拟审计对总计 12740 条城市街道进行步行环境评价，并剖析结果背后的现实问题、原因和对策。实证结果验证了评价指标体系的有效性和方法的可行性，同时也明确了中国城市街道步行环境存在的问题，为精细化规划和管理城市慢行交通系统提供思路和建议。

摘要ABSTRACT
The existing studies concerning walkability mainly focus on the characteristics of the built environment that could encourage walking. However, few discussions have been reported regarding the influence of the street environment on walking experiences. In this study, a walking environmental assessment method was proposed, involving the nine indexes of crossing facilities, street planting, building aspect ratio, street furniture, isolation for non-motor vehicles, width of the sidewalk, illegal parking, sidewalk disrepair, and bike-exclusive lanes. This method was applied to evaluate the walking environment of 12,740 city streets in 71 urban vitality centres of 50 typical Chinese cities by combining street images and virtual audits. In addition, the practical problems, causes, and strategies behind the scores were analyzed. The empirical results validate the feasibility of the proposed method in revealing problems of the walking environment in Chinese cities. Research conclusions provide suggestions to refine urban planning and management of non-motorized traffic systems in cities.
