基于分形理论的城市区域空间结构优化研究——以兰州-白银城市区域为例
Optimization research of urban areas space structure based on fractal theory——A case study of Lanzhou and Baiyin urban areas
摘要
Abstract
The paper takes Lanzhou and Baiyin urban area as an example and analyzes quantitatively the regional spatial structure based on the fractal theory gathered dimension, grid dimension and the correlation dimension model.The results show that urban space distribution center to a density attenuation state around Lanzhou, the attractions surrounding towns near center city induces gradually with the distance increasing.At the same time, most towns heavily focus on geographical factors (the traffic lines or rivers), their self-organization evolution in space structure has an optimal trend, however,their spatial correlation degree and space interaction degree is general.In order to promote space structure optimization in urban area of Lanzhou and Baiyin, the paper puts forward three space optimization aspects from three levels of the point, line and area.关键词
