基于分形理论的新疆伊犁河谷地区城镇体系研究

Urban system fractal research in Ili Valley of Xinjiang Uygur Zizhiqu

运用分形理论从等级规模和空间结构两方面分析了新疆伊犁河谷地区城镇体系结构特征,得出伊犁河谷城镇体系具有分形特征;城镇规模结构分布较为集中,中等位序的城市较多,人口分布低水平均衡,处在城镇体系发展的初级阶段;城镇空间结构由于受到山地河谷地形和社会经济条件的影响,城镇沿河谷呈条带状分布,城镇间联系不紧密,空间相互作用强度较弱;对伊犁河谷地区城镇体系结构提出了建议。

This paper discusses the size distribution and space distribution of Yili Valleyin in Xinjiang with the fractal method.The results cities and towns is not close,the capacity of spatial interaction is weak.According to the conclusions mentioned above,the paper puts forwardshowed that the urban system have the fractal properties;The size-scale structure is relatively concentrated and the quantities of middle scalecities are more than other ones,but the urban system is stillata low level equilibrium and the initial stage of urban system development.Due tomountain valley topography and the impact of socio-economic conditions,the system distributes along the fiver into zones,the linkage between some suggestions for developing the urban system of Yili Valley.
