摘要
以夜间灯光数据作为基础,借助线性回归和柯纳尔密度分析方法对益阳市城市空间结构的演变过程进行分析,可见益阳市夜间灯光亮度增加的过程与市域城镇化过程呈现较为明显的线性关系,城市空间结构及其演变过程表现出较为显著的椭圆形结构形态,中心城区的空间范围也呈现出椭圆形结构形态,中心城区的几何中心不断向东南方向移动。总体来看与城市空间结构的同心环模式、扇形模式和多核心模式等经典模式存在显著差异。然而,益阳市城市空间结构的圈层以及向东南方向延展的特征又与同心环模式和扇形模式呈现出一定的相似性。
The evolution process urban spatial structure of Yiyang city is studied by means of linear regression and kernel density analysis based on the night-time light data.There are four conclusions in this paper.First,there is an obvious linear relationship between the night-time light brightness and the process of urbanization in Yiyang city.Second,the urban spatial structure and its evolution process show a relatively obvious elliptic structure shape.Third,the spatial form of the central city also presents an obvious oval structure shape.Fourth,the geometric center of the central city is moving to the southeast.On one hand,the characteristics and evolution process of the urban spatial structure of Yiyang city show an obvious elliptic structure shape,which is significantly different from the concentric ring model,fan model,multi-core model and other classical models of the urban spatial structure.However,on the other hand,the spatial structure of Yiyang city has some similarities with the concentric ring model and the fan model.
