中文摘要：

居民日常活动空间直接反映其对城市空间的利用状况及生活质量，从而得到地理学、规划学、社会学等领域的关注。中国城市在市场化转型、快速城市化等背景下，社会阶层分化与居住空间分异日益明显，城市社区无论在社会构成还是在建成环境上都呈现出显著的空间分异。基于对北京城市居民活动日志问卷调查数据，借助GIS可视化与空间分析方法，通过对北京城市不同类型社区居民日常活动的时空分布、活动空间形态及面积等特征的比较，揭示不同社区居民的日常活动空间的社区分异，试图将基于人口属性、设施供给的社区分异研究拓展到基于日常行为的居民对城市空间利用的社区分异。

英文摘要：

Residents＇ daily activity spaces might directly reflect the situation of how they make use of urban space and the quality of life, which have attracted much research attentions from academic fields of geography, ur- ban planning and sociology. Under the background of market-oriented transition and rapid urbanization, there have been seeing an increasing social classification and spatial differentiation, and there also have been seeing obvious community differentiation on both social constitution and the built environment. Based on activity diary survey of Beijing urban residents, and aided by GIS geovisualization and spatial analysis, this paper compared residents＇ space-time activity distributions as well as geometric configuration of activity space among different types of urban community, by which to profile the community differential on daily activity space. This paper try to further extend community differentiation research from the respective of individual space-time activity.
