摘　　要：基于重力模型,利用非农业人口、GDP、建成区面积等进行综合运算,研究了重庆及周边城市的吸引关系,并进行了城市群划分,揭示了各城市之间内在的发展关系。研究结果显示,重庆及周边城市形成了3个一级城市群、3个二级城市群和若干个抱团发展的城市。本研究对重庆及周边城市规划政策的制定和发展方向的研究具有一定的参考价值。Based on the gravity model,we used the non-agricultural population,GDP,and the built-up area to research the attraction relations between Chongqing and surrounding cities.And then,we divided the urban agglomeration,and revealed the inner development relation among the cities.The results show that Chongqing and surrounding cities form three first-class urban agglomerations,three secondary urban agglomerations and a number of small cities.This research has a certain reference value for the formulation of urban planning policy and its development direction in Chongqing and surrounding cities.
