| 摘 要： | 运用分形理论从等级规模和空间结构两方面探析了粤西地区城镇体系结构特征。研究结果表明，粤西城镇等级规模分维数q为0．9884〈1，说明粤西地区城镇规模等级结构较为分散，首位城市的垄断性弱，小城镇数目较少，处于中间位序的城镇数目较多，城镇体系结构不完善。城镇空间关联维数D为0．9304〈1，说明粤西地区的城镇体系在空间分布上比较集中，空间联系较为紧密，城镇之间具有加强联系、共同发展的先天条件。据此提出了粤西地区城镇体系发展的建议。

| Abstract: | Fractal theory was used to analyze the hierarchical scale structure and the spatial distribution of county region in western Guangdong Province.The results show: the fractal dimension of size-scale structure(q) is 0.9884<1,indicating the loose size-scale structure and the weak law of the primate city;the number and the scale of the small cities showed low-level development,and the number of middle-rank cities is more so the urban system of county region in western Guangdong is not developed;the fractal dimension of spatial distribution(D) is 0.9304<1,which shows big correlation of towns and close spatial distribution with advantages of strong ties and mutual development.At last,some suggestions for how to optimize the urban system of county region in western Guangdong were given. |
