摘　　要：通过测算城镇规模分布的首位指数、不平衡指数和分形维数,发现:广西城镇规模分布较为集中,人口分布比较均衡,中小城市比较发育,首位城市垄断作用不突出.通过对2002～2009年广西城镇规模分布的首位指数、不平衡指数、分形维数的分析,得出:广西首位城市的首位度在提高,但垄断作用一直不够突出;城镇规模分布均衡程度高,接近最优分布.根据上述结论,提出了相应的优化措施.Primacy index, unbalanced index and fractal dimension show that the city -size distribution of Guangxi is relatively concentrated; population distribution is comparatively balanced; medium -sized and small cities have grown well; monopoly degree of the primate city isn＇ t prominent. Based on the analysis of the pri- macy index, unbalanced index and fractal dimension of city - size distribution of the urban system in Guangxi from 2002 to 2009, it is found that the primacy drgree of primate cities is rising, but the monopoly function has not been very prominent; the city - size distribution is very balanced and close to superior distribution. Accord- ing to the above - mentioned conclusions, some corresponding optimization measures are put forward.
