从人口角度探求城市空间结构的演化和区域发展规律是城市与区域研究中比较常用和成熟的思路。本文利用人口普查资料中总人口和迁入人口数据，分析京津冀北地区人口空间分布变动和迁入的空间特征。研究发现近十年京津冀北地区人口分布仍是多中心集聚扩散并存。人口分布变动主要由迁移变动引起，中心城市仍是主要的人口迁入地，但与外围县的迁入人口比例有所下降。迁入人口向次中心城市集聚，且在市辖区的分布日趋集中。各市辖区有着不同的人口迁入特征，北京天津迁入人口数量多范围广；唐山、保定、沧州迁入人口总量高，但以省内为主；秦皇岛、廊坊两市，迁入总量不高，但外省迁入比例高，迁入平均范围广；张家口、承德以省内迁入为主，外省人口主要来自于北部相邻省份。

Seeking for the changes of the regional spatial pattern from the perspective of the population is a common and mature idea of city and regional studies. This paper focused on the spatial distribution of the population and migration characteristics, in the north of Beijing-Tianjin-Hebei, based on the census data. We found that the distribution of the population has still been multi-centers and agglomeration diffusion coexist, which mainly composed of migration changes. Each area has different migration characteristics. The migration of Beijing & Tianjin has the largest amount and range. Tangshan, Baoding & Cangzhou have high population density and there are many migrants while most of them are from Hebei. The number of migrants in Qinhuangdao & Langfang is not large, but a large part of which is interprovincial migration. Zhangjiakou & Chengde have low population density and little migration scale, and most of the interprovincial migrants are from Inner Mongolia.
