利用经济距离模型对黔中城市群范围进行界定,在此基础上,借助分形模型及城市空间相互作用强度模型对黔中城市群空间结构进行测度. 研究结果表明:黔中城市群包括贵阳市、开阳县、息烽县、修文县、清镇市、遵义县、遵义市、安顺市、平坝县等22个城市;城市主要集中于铁路及高速公路沿线;城市间的交通网络发育较为成熟,空间可达性较好;城市空间分布属于典型的集聚型,且集聚程度很高;贵阳市和安顺市是黔中城市群中比较重要的2个节点;城市群的空间联系方向以贵阳市为中心,呈圈层状向外辐射以及沿兰海、沪昆高速公路呈轴线状拓展. 据此,提出了黔中城市群未来空间结构优化的思路,即打造"一圈"、"两主轴"、"两次轴",培育"一个增长极".

The paper firstly defines the scope of urban agglomerations by using economic distance model.On this basis,measuring on the spatial structure of urban agglomeration in central Guizhou by means of the fractal mod-el and intensity of urban interaction model.The results indicate that the urban agglomeration in central Guizhou in-clude 22 cities, they are Guiyang City, Kaiyang County, Xifeng County, Xiuwen County, Qingzhen City, Zunyi County, Zunyi City, Anshun City, Pingba County and so on;the cites are mainly concentrated on both sides of the railway and highway;the development of transport network among cities is relatively mature, space accessibility is better;urban spatial distribution exhibits typical characteristics of centralization,and the degree of centralization is very higher;Guiyang City and Anshun City are two most important nodes in urban agglomerations;the spatial con-nection direction appears in a circle-shape which radiates externally around Guiyang City,and expands linearly a-long the Lanhai,and Shanghai-Kunming highway.Based on the above conclusions, the author puts forward the opti-mization ideas of the spatial structure of urban agglomeration in central Guizhou that creates a"circle","two main axes","two secondary axes"and cultivates"a growth pole".
