摘　　要：借助GIS技术揭示了新时期北京市商业土地出让的空间分布特征、动态演变,探讨了对城市土地利用和空间发展的影响。北京商业土地出让的分布由二环至四环逐步向五环外转移,城市功能拓展区出让数量减少,城市发展新区增加,旧城区分布一直比较集中。商业集聚区表现出旧城高集聚区面积增大、远郊新城中低集聚区数量增多、城郊大型居住区集中程度提高等特征。商业土地出让时空格局动态演变存在显著差异,东北方向扩展距离较远,波动大;西北与西南方向外延扩张典型,扩展距离远,年均速率大;东南方向空间扩展不显著。最后,探讨了商业土地出让时空格局演变在土地利用方式与效率、商业郊区化、功能疏解与职住分离等方面产生的影响。With the aid of GIS-based spatial analysis methods, the paper illustrates tempo-spatial patterns of leased commercial land lots in Beijing. It indicates that the leased commercial land lots put forward from the second ring road to the outer of the fifth ring road. The number of it in urban function extended districts has declined, in new districts of urban development has increased, and in core districts of capital function maintains concentrated distribution.As each quadrant has local conditions, there are significant differences about the dynamic of leased commercial land lots in different quadrants. Then the paper uses the kernel method to analyze the spatial cluster of leased commercial land lots. It demonstrates that the area of the high-level clusters in core districts gets larger, the numbers of the medium and low level clusters in the new towns increase, and in the large-scale suburban residential area the clusters get more concentrated. In the end, the paper discusses the effect of tempo-spatial patterns＇ evolution of leased commercial land lots from the aspects of urban land use, retail suburbanization, function evacuation and the spatial mismatch between housing and employment.
