摘　　要：在Arcgis9.0地理信息系统的支持下,采用普通克立格插值和反距离加权插值两种方法研究京津地区人口的分布规律,结果表明:在主城区点效应和主干道交通的廊道效应作用下,该区的人口分布趋势是以北京和天津的中心城区为高密度人口聚集区域,并沿主要交通动脉由中心向周围地区呈梯度递减变化,在两城市间沿京津交通廊道形成了一个人口持续增长和密集分布的廊道区域。近几年该区域的中心城区人口密度逐渐减少,城市外围区人口增加,人口郊区化发展迅速。With the support of Arcgis9.0, this paper analyses the population spatial feature through the Ordinary Kriging and IDW methods. The result shows that, according to the main city-region point effect and main traffic roads corridor effect, the region＇s population distribution tendency is as follows： Beijing and Tianjing＇s main city-region is the agglomerative area with a high population density and it spreads down to the neighborhood area while the density is decreasing during the process, a growing and thick population corridor region is formed between the two cities. Meanwhile, the main city-regions＇ population density was declining in the past years; the result also indicates that population suburbanization of Beijing-Tianjin area develops very quickly . However, the distribution of the population will be better-proportioned in the whole area in the long run.
