| 摘 要： | 利用城市结构的分形模型和城市产出的C-D模型，从国家、区域和典型城市三个层面对1983—2006年我国城市人口、土地和产值三者之间的非线性关系进行了分析。结果显示：我国大部分城市在研究时段内具有分形特征，标度因子值均为分维，大部分城市系统在向结构优化的方向发展。

| Abstract: | Based on the fractal model and the C-D function,this paper analyzes the non-liner relationship between urban population,urban land and output of cities in China during 1983-2006 from aspects of the nation level,the region level and the city level.The results show that,most of cities in China have the characteristics of the fractal patterns of self-affinity;the scale factor also has the characteristic of fractional dimension,and most cities system are moving toward the goal of structure optimization. |
