摘　　要：在GIS技术的支持下,利用分形几何学的相关原理研究平顶山市域城镇体系空间结构.经过测算,聚集维数1.72,说明该城镇体系在空间上围绕中心城市呈聚集态分布,容量维数1.46,信息维数1.484,表明该城镇体系的空间结构具有多重分形性态,系统内城镇分布沿着主要交通路线,城镇体系空间结构呈现条带状分布.Research on the architecture of urban space is one of the main contents of the research of urban system. Transmission and switching elements of urban body system through the material flow, energy flow and information flow, interdependence, competition, cooperation development, the region of urban spatial distribution showed certain rules, this is the urban system spatial distribution of self similar fractal structureD3. In this paper, based on the GIS, the fractal geometry theory carries on the analysis to the Pingdingshan urban system spatial structure. We find the spatial layout of urban system in Pingdingshan is more dispersed, along the main traffic trunk, the degree of urban spatial association general, the spatial structure of urban system presents a banding distribution.
