摘　　要：从时空间行为研究的新视角透视人类活动与城市空间的关系,基于西安市2015年7月到12月居民微博签到数据,采用标准置信椭圆与叠置分析对居民周末活动空间进行测度。结果发现:西安市居民周末活动空间以明城墙区域为核心区并呈东北—西南方向分布,覆盖钟楼、小寨、高新等主要商圈;活动点以长安路沿线为最集中区域,日均活动范围为40.34km2,日均出行距离为12.24km,同时个体间出行活动空间差异较大。研究表明,城市空间的迅速扩张及交通设施的快速发展使得城市居民的活动空间表现出新的特征,周末作为居民日常休闲娱乐的主要活动时段与周内上班、上学通勤活动有着明显差异。From the new perspective of spatial and temporal behavior, the relation of human activity and urban space are studied in the study. Based on the latitude and longitude coordinates which were released by micro-blog users of Xi＇an city from July to December in 2015 as the data source, the residents＇ weekend activity space was measured by using GIS spatial analysis, standard confidence ellipse and overlay analysis methods. It was discovered that the activity points of Xi＇an urban residents on weekends are distributed from Northeast to Southwest and concentrated on Chang＇an road. The average area of residents＇ daily activity is 40. 34 kmz on weekend, and the average daily distance of residents＇ travel is 12.24 km. The difference of travel activity among individuals was great. The results indicated that the urban residents＇ activity spaces show some new features because of the rapid expansion of the city and the speedy development of the transportation. While, as the main activity time of residents, daily entertainment, the weekends show significantly different characteristics compared with weeks.
