基于分形理论的海南省城镇体系研究

Urban Systems of Hainan Province Based on Fractal Theory

运用分形理论和方法,对海南省城镇体系的等级规模、分布特征和空间结构相关性进行实证研究.结果表明:海南省城镇体系中高等级城市数量少,城市规模小,等级低,城镇体系结构不健全,处于较低发展阶段;城镇体系等级规模结构松散,人口分布均衡性差,人口集中向大城市发展,区域发展依靠首位城市的带动为主;城镇间的空间关系不够紧密,空间相互作用不强,但海南省关联维数D接近1,空间分散程度并不高;城镇间的交通关联度较高,交通优势明显;海南省国际旅游岛建设促进了城镇体系的成长和优化.

In the report, the fractal theory and method were used and the empirical study on the scale and spatial correlation of the urban system of Hainan was performed. The results indicated that the structure of the urban system of Hainan province is not perfect, the grade is low, and which is still in the lower stage; The scale structure of urban system of Hainan is relatively loose, and the degree of population distribution is quite different; The spatial relations of cities and towns are not close enough, the spatial interaction is not strong, however, the correlation dimension D of Hainan is close to 1, and the spatial dispersion degree is not high ; The correlation degree between cities and towns is higher, and the traffic advantages are obvious; The construction of international tourism island improved the urban system of Hainan. On the basis of it, some suggestions on optimizing the urban system of Hainan were put forward.
