中文摘要：
研究目的：揭示2001年以来北京市住宅用地出让的空间分布与动态演变，探讨增量住宅用地空间演变带来的城市土地利用方式的变化。研究方法：欧氏距离分析法，核密度估计法。研究结果：近郊区住宅用地出让所占比重下降、中心区和远郊区比重上升；住宅出让高集聚区主要分布于近郊大型居住区和旧城区，中、低集聚区主要分布于远郊新城和交通廊道沿线的乡镇；长安街以南地区住宅用地外延扩张较典型，以北内部填充式发展较明显。研究结论：新时期北京市住宅用地存在旧城区有机更新、近郊区内部填充式发展和远郊区分散组团式发展三种方式，并非简单的圈层式蔓延。
英文摘要：
The purpose of this paper is to study the spatial distribution the data set of leased residential land lots since 2001. Its impact on c change of residential land in Beijing based on hanging of land use pattern is also discussed. Methods of Euclidean distance and the kernel density method are employed. The results indicate that the proportion of leased residential land in the inner suburb districts had declined, but those in the urban center and outer suburbs increased. The most intensive clusters mainly locate at the large-scale suburban residential area or the urban center. The medium and low intensive clusters mainly locate at the new town areas and the towns along the main radial transport corridors. It is obvious for the sprawl for the leased residential land lots in the areas south to the Changan Avenue; however, there is an obvious infill phenomenon in the areas north to the Avenue. It is concluded that there are three types of residential land use patterns in Beijing including urban renewal in the center, plot infilling in the inner suburb districts, and spatially clustering in outer suburbs.
