本文探讨了城市体系空间分布的分形特征,东北地区城市体系的空间结构,包括随机聚集分维的测算比较、分形结构因子的度量等的分析,以及东北地区城市体系相互作用与形成机制等.
The paper made a preliminary study on the spatial structure of systems of towns which take Shenyang,Changchun and Harbin as centers respectively in northeast China. A law is found that the spatial structure becomes gradually loose while the level of aggregation tends to rise from the south to the north based on the measurement and calculation of fractal dimension and fractal structure factor. The authors discussed how the spatial patterns formed and lastly, put forward suggestions to improve the supervise of the systems of towns in northeast China.
