城市公共空间使用后评价数据的特性分析

城市修补生态修复是今后城市规划工作的主导方向。使用后评价（POE）是针对城市已建成空间环境的使用感受和体验评价，对开展城市双修有着举足轻重的指导意义。POE评价定性化数据记录“人”对场所空间直觉认知，具有序数属性、类别属性和数值属性，同时兼有统计特征、时空特征、可挖掘及可视化特征。POE定性化数据属性分析表明，不同类别的人群对公共空间及其现有配套设施有不同感知及改进需求，且具备可度量态势；其数据特征表明，使用者对空间的共性活动规律以及对各项设施配备的舒适度等信息是可以挖掘并可通过可视化图式方式表达，这对帮助解决城市双修中“修补什么”的疑问，同时为继续开展“怎样修补”的可视化研究打下基础。

Characteristics of Post Occupancy Evaluation Data of Urban Public Space

Urban repairing and ecological restoration is the main direction of urban planning in the future. Post occupancy evaluation （POE） aims at evaluating the experience of urban built space environment，providing important guiding significance to carry out urban repairing. The qualitative data of POE record the perception of people in the public space，which possess the ordinal，category and numeric attributes，as well as the statistical，spatiotemporal，mining and visualization features. Analysis of POE qualitative data shows that different groups of people have different perception and improvement requirements for public space and the existing facilities，which can be expressed by the measurable means. Meanwhile，POE data characteristics show that the user’s activity rules in public space and the comfortableness of the facilities can be interpreted and expressed by the way of visualization. Therefore，this work will help in solving the problem of what needs to be repaired in urban repairing，and is also beneficial to carrying out the further research on visualization.
