摘　　要：目的对西北地区城市等级结构与经济影响区范围进行界定,并研究城市经济影响区的空间联系通道,为西北地区城市建设与区域合作联系提供基础研究。方法运用城市地理学与经济地理学方法,依托GIS空间数据分析技术研究了西北五省城市的等级结构以及中心城市与腹地形成的经济影响的界限,同时提出了西北地区各城市经济影响区的联系通道以及影响城市经济影响区范围的因子。结果西北地区中心城市可分为四级等级结构,西北五省中,城市与省区间城市发展水平与规模差距大,城市经济影响区范围差异显著;城市发展水平、交通通达率、人文社会因素以及自然禀赋等因子是影响城市经济影响区范围的主要因子;西兰新、西兰青、西兰银、"门户"通道构成了西北地区城市区际协调与空间组织的联系纽带。结论西北地区城市间存在显著等级结构,各城市经济影响区之间有较为明确区间及区际通道。Aim To define the city hierarchical structure and economic influence area in Northwest China,and study the urban economic influence area in terms of space connection channel,and provide the basic research for the urban construction and the regional cooperation in the Northwestern Region.Methods By using urban geography and economic geography,based on the GIS spatial data analysis technique,the five provinces in the Northwest China are studied in terms of the city hierarchical structure,the center city and its hinterland economic effects of boundaries,at the same time the connection channel of urban economy influence area,as well as the factors affect the urban economy influence area.Results In northwest China,center cities can be divided into four levels of structure.In five Northwestern provinces,gaps exist among the cities and the provincial capital are areas in the urban development level and the scale disparity,while urban economic influence areas are significantly different.The main factors in the urban economy influence area are city development level,traffic access rate,social factor of humanity and natural factors.Xi-Lan-Xin,Xi-Lan-Qin,Xi-Lan-Yin and ＂Portal＂channels have constituted interregional coordination and spatial organization link in Northwestern China.Conclusion Significant hierarchical structure exist among cities in the Northwest region,there are fairly clear interval between urban economic influence areas and regional channels.
