西北民族地区城市地域空间结构研究

A Research into the Regional Structure of City Arrangement in Ethnic Areas in Northwest China

城市化是民族地区实现现代化的必由之路。西北民族地区城市地域空间结构受到地理因素的影响,呈现出低密高疏的垂直分异和河谷平地密、高原山地疏的水平分异的特征。由于西北民族地区城市数量少及规模小的原因,从空间结构上看,省(区)际分布差异十分明显,表现为两个城市空间重点;从区域内的城市集聚区看,形成了三个块状城市集聚区:宁夏平原块状城市集聚区、兰州-西宁块状城市集聚区以及乌鲁木齐城市集聚区。

Urbanization is the only way to modernization of ethnic areas. The city arrangement in Northwest China is characterized by the vertical difference of 'being intensive in low-level land and being scattered in highland' and the horizontal difference of 'being intensive in valleys and being scattered in plateaus'. From the perspective of space arrange, the differences among provinces and regions are noticeable; from the perspective of assembled areas, three assembled areas are formed-one is Ningxia plain, another Lanzho-Xining and the third Urumqi.
