摘　　要：基于分形理论计算并分析了宁夏城镇体系等级规模结构.结果表明,宁夏城镇等级规模分形维数为1.17,这说明宁夏城镇体系中处于中间位序的城镇数目较多,分布比较集中,且人口分布较为均衡;但是城市规模分布双对数图也表明宁夏城镇规模等级不连续,结构不完善.所以在宁夏城镇化发展规划中还应适当调整城市发展思路,加速城市体系向着更优化的方向演化.The paper study the urban system of Ningxia based on the fractal theory. The fractal dimension was calculated to describe the features of the system by the numerical simulation. It is shown that its development is in balance situation due to urban primacy indexes. But the urban structure is slightly discontinuous.
