城市化进程的加快和房地产业的快速发展使居住小区时空复杂性日益突出,居民的择居行为和居住区位都在不断地发生变化。依据统计资料,结合实地调查和电话访查收集到1998~2006年大连城市居住小区的相关数据,运用GIS的空间分析功能,从实证与定量分析角度揭示出大连城市居住小区10年来的时空演化分为快速增长、缓慢调整和井喷式膨胀三个阶段;在趋向于城市边缘、沿交通干线、自然资源优美地区布局与临近高新技术园区、大学园区布局四种区位指向性下,居住小区的空间演化模式呈现出圈层外溢、扇面拓展和组团聚集三种模式。

The expansion of urban residential space is a continuously dynamic process, and displays different spatial characteristic in the different stage of urban development.Along with the rapid development of urbanization and real estate, the temporal-spatial complexity of residential quarter is prominent day by day, and residents’behavior of choose residence place and residential location are constantly changing.First, based on statistical information, combining with the field surveys and telephone visits collects the relevant data of urban residential quarter from 1998 to 2006;using spatial analysis function reveals the time-space evolution of urban residential quarter in the last ten years from empirical and quantitative angle;the process of evolution could be classified into three stages:rapid growth, slowly adjustment, and expansion of blowout type.The former two stages, residential space expansion takes the release of rigidity demand on the initial marketability and the guidance of transportation infrastructure construction as the main driving force, the town center plot is a mainstream, and in the later period the obvious residential quarter suburbanization phenomenon appears.On the third stage, as the non-native population gradually increases, the transportation network gradually improves and the private vehicle massive emergences, the expansion of residential quarter is faster than infrastructure construction, the community environment and the natural landscape become the most important factor of the residential quarter layout, the suburbanization become the mainstream.Second, the article analyzes the "location direction" rule which is followed by the characteristic of space-time dynamic change.The development of residential quarter is influenced by the location condition, the region infrastructure condition (transportation, education, health and so on), the environment condition (nature, society, humanities environment) and presents different location directions.Dalian mainly has following four kinds of situation:the urban fringe layout, traffic road layout, and approaching hi-tech garden and natural resources layout as well as near university layout.At last, Dalian is the city which develops unceasingly along the harbor, and is limited by multi-mountain terrains;the residential space expands along the old city with circle structure while spreads to city fringe area, meanwhile depends on the traffic artery to extend to the hinterland in sector and to form the relatively concentrated spatial structure of the residential group.The residential spatial expansion urges the formation of new urban business center, impels city space restructuring.The development of residential space has accelerated the suburbanization of residence and residential space differentiation.
