摘　　要：兰州市是西北干旱地区典型的河谷盆地型城市 ,通过分析了兰州市域地域结构的特征、模式以及市区的结节地域和均质地域 ,讨论城市地域结构形成与发展的影响因素。兰州市域地域结构呈现带状分散多中心组团结构形态 ,而且各功能区的均质度、紧凑度都比较低 ,城市结节地域结构虽然发生了不同程度的变形 ,但仍遵循六边性构造的理论模型。Lanzhou is a typical valley basin city in the northwestern China. This paper analyses the status quo's feature and organized model of internal structure and outer morphology of Lanzhou, and nodal region and homogenous area of urban district of Lanzhou. The factors affecting the forming and development of urban area structure of Lanzhou are discussed in the paper. Urban area structure of Lanzhou manifests dispersing and zonal multi center spatial structure. Both of the homogenous degree and agglomerating degree of Lanzhou's urban district's functional area are very low. The average homogenous degree of inner and outer industrial area in Lanzhou's urban district are all below 1.07,and the average agglomerating degree of it are all below 0.27. The agglomerating degree of Lanzhou is below 0.03, which proves the belt feature of Lanzhou. The nodal region structure of Lanzhou's urban district still theoretically complies with Hexagon Structure Modal although the rank system of it isn't perfect because of the effect of natural conditions, especially landform. Lanzhou′s unique natural condition and industrial development have played a great role on the development of its internal structure and outer morphology. Urban area structure of Lanzhou manifests dispersing and zonal multi center spatial structure. The circle structure of urban area structure of Lanzhou from inner to outer place can be outlined as belted core parts, inner suburban district producing vegetables, melon and fruit in valley belt of the Huanghe(Yellow) River and the Huangshui River, outer sector satellite towns, outer agricultural area in the valley and others that concretely shows CBD commercial and serving center, fringe belt of urban center, inner and outer industrial area, satellite towns and agricultural suburbs. Fringe belt of urban center has the integrated function consisting of commercial function, social function, cultural function, administrative function, medical function, insurance function, financial function, and light industrial fun
