摘　　要：基于分形理论对广西城镇体系空间结构进行研究,发现广西城镇空间分布具有统计分形特征。关联维数和牛鸦维数测算结果显示:广西城镇高度集中于河流和交通线两侧,城市之间的交通网络发育较为成熟。聚集维数测算结果表明:广西城镇空间分布不均衡,密度差异大,"双核心"结构明显。认为这些特征的出现是地理位置、自然条件、历史、交通、政策等因素共同作用的结果。Abstract： The fractal analysis of spatial structure of urban system shows that the distribution of cities in GuangXi exhibits a statistical fractal feature. The results of correlation dimension and Cattle-Crow dimension indicate that the cities in GuangXi are highly concentrated in both sides of rivers and traffic lines, with convenient communication among them. The results of aggregation dimension show that the spatial distribution of cities in GuangXi is imbalanced, with large difference in urban densities and an obvious structure of ＂double cores＂. The appearance of these characteristics is considered as the results of cooperation of many factors such as geography locations, natural conditions, histories, policies, etc.
