| 摘 要： | 运用分形理论和方法对齐齐哈尔市城镇体系空间结构的聚集维数、网格维数、关联维数进行了测算．三种维数的测算结果表明：57个镇的空间分布从市区向四周密度是递增的，这是不正常的，各城镇以近似于几何中心的富裕镇表现出了较好的聚集形态；57个镇及市区空间分布的总体均衡性适中；9个县城及市区的空间分布比较集中，空间关联性较强．最后，对测算结果所揭示的问题进行了进一步的深入思考．

| Abstract: | Calculated the aggregation dimension, grid dimension and correlation dimension which reveal the spatial structure character of town system in Qiqihar with the fractal theory and method. The fractal dimension calculations indicated that the town system shows a good aggregative form surrounds the spatial center Fuyu, the spatial distribution of 57 towns and urban area is overall balanced and the 9 main towns and urban area are concentive and well correlated. At last, made a further thinking of the problems that revealed by the calculations. |
