中文摘要：

对广州36个中产阶层聚居区881个中产阶层进行工作日与休息日活动日志问卷调查的基础上,运用时间地理学和多层次聚类方法,探讨中产阶层日常活动时空路径的特征及影响因素。研究发现中产阶层工作日活动路径根据就业地不同而呈现差异化的路径形态,可聚成无工作的直线路径和有工作但通勤距离不同的曲线路径等5类;休息日活动路径根据活动距离和活动持续时间不同而呈现多样化的路径形态,可聚成近家型活动的短距离曲线路径、购物与用餐为主的中短距离曲线路径、购物与外出办事为主的中长距离曲线路径和休闲与用餐为主的长距离曲线路径等6类。此外,不同自然、社会经济和环境属性的中产阶层活动路径特征各不相同。个体特征、城市空间结构、产业和制度因素综合作用于中产阶层的日常行为,导致中产阶层日常活动时空路径呈现独特特征。研究有助于揭示中产阶层的日常活动规律,为提高城市社会经济活力和完善城市精细化管理提供参考。

英文摘要：

This paper mainly discusses the characteristics and factors that influence space-time paths of middle-class daily activities,using the time geography and multi-level clustering methods,on the basis of the questionnaire survey on the working and weekend day activity diaries of 881 middle classes in 36 middle-class neighborhoods. The results show that the activity paths of middle class have differential forms on the working day according to the work locations,and can be clustered into 5 types including the straight path without work and other curve paths with stable jobs but different commuting distance. While,the activity paths of middle class have diversified forms on the weekend day according to the activity distances and durations,and can be clustered into 6 types such as curve path with short distance,middle-short distance of middle-class shopping and dining primarily,middle-long distance of middle-class shopping and errands primarily,and long distance of middle-class leisure and dinning primarily from home,etc.In addition,the characteristics of activity paths are various with different natural,socioeconomic and environmental middle classes.On the whole,the individual futures,urban space structure,industrial and institutional factors comprehensively play a vital role on the daily activities of middle classes,which lead to the space-time paths of those having unique characteristics.The study on the space-time paths of middleclass daily activities contributes to reveal the daily routine of the middle class,and provides important basis for urban socioeconomic dynamic and urban refined management.
