摘　　要：基于引力模型和潜力模型,测度2000,2015年京津冀城市群各城市的空间作用强度、方向与范围,研究京津冀城市群城市体系的空间结构及其演变特征。结果表明:北京(市区)和天津滨海新区的吸引区范围不断扩张,为更多城市提供了发展机遇,但也导致京津周边各地级市市区吸引区范围的减小;河北南部各地级市市区吸引区范围变化不大,但潜力等级降低,石家庄(市区)在南部地区的增长极地位愈发凸显;大部分节点城市的等级降低,河北高等级节点数量减少尤为显著;非地级市市区的低等级节点城市增多,且大都位于石家庄Ⅰ级城市体系;京津冀城市体系空间结构更为稳定和成熟,但三大Ⅰ级城市体系均存在某一级节点城市的缺失,基本架构仍有待完善。Based on the gravity model and potential model,the economic linkage intensity,effect direction and effect range of cities in Jing-Jin-Ji urban agglomeration in 2000 and 2015 were measured.The results show that:Firstly,the gravitation region of Beijing(urban district)and Binhai New District have extended outwards continuously with time and causes the decrease of gravitation region of major central cities located in circumjacent area,however,the gravitation region of central cities in southern Hebei change little and the growth pole position of Shijiazhuang(urban district)has been increasingly highlight;Secondly,the grade of most node cities get reduced,especially for the node cities located in Hebei Province;Thirdly,the lower grade node cities which are not municipal districts increase and are mainly distributed in the 1st urban region with Shijiazhuang(urban district)as the center;Finally,the spatial structure of Jing-Jin-Ji urban systems has become more stable,but there is a lack of node city with a certain level in the three 1st urban regions and the basic structure remains to be perfect.
