基于引力模型的辽宁省城市空间格局研究

Study on Urban Spatial Pattern of Liaoning Province Based on Gravity Model

以万有引力理论为基础,选取相应的指标,构建引力模型公式和断裂点模型公式,再通过Arc Gis软件分析辽宁省城市空间格局。结果表明虽然辽宁省城市群已经形成了沈阳经济区和沿海经济带的城市空间格局,但是辽宁省城市的屏蔽效应显著,边缘城市发展落后。提出了以鞍山-营口为重要节点连接沈阳经济区与沿海经济带,发挥沈阳经济区与沿海经济带的协同作用,以促进辽宁省城市协调发展。

Based on the theory of gravitation,the corresponding indexes are selected to construct the gravitational model formula and the breaking point model formula.The urban spatial pattern of Liaoning Province is analyzed by Arc Gis software.The results showalthough the urban agglomeration of Shenyang Economic Zone and coastal economic zone has formed the urban spatial pattern of Shenyang city,the shielding effect of the city in Liaoning province is significant and the marginal city is lagging behind.This paper puts forward the synergistic effect between Shenyang Economic Zone and coastal economic zone by connecting Anshan-Yingkou as an important node for Shenyang Economic Zone and coastal economic zone,and promotes the coordinated development of cities in Liaoning Province.
