摘　　要：概述了国内影响格局的相关研究成果,从市场经济及西部大开发的背景出发,分析兰州与周边部分省会城市开发格局的关系。通过场强模型、市场断裂点模型及最大联系强度模型,从理论上定量计算了兰州与它们之间的空间影响范围及联系强弱状况。计算结果表明:①兰州对省内的东部地区、南部边境及西北地区影响弱;对北部、西部影响力强,向北可达宁夏境内、向西可达青海境内。②兰州对外联系以西宁为主,与银川联系急需加强;与西安联系是重要方向;与成都联系是新时期发展需求;通过乌鲁木齐联系边贸。③经济联系类型包括紧密型———兰州-西宁;摇摆型———兰州-西安、兰州-银川;松散型———兰州-成都、兰州-乌鲁木齐。Correlative study outcomes of effect pattern at home were summarized in the paper. Based on the background of market economy and development of the west regions, the research analysed the relationship of developmental pattern between Lanzhou and peripheral capital cities. Through model of field intensity, model of market breakpoint and model of maximum correlative intensities, spatial effect ranges and interactional intensities between Lanzhou and these cities in theory were quantificationally calculated. The results showed： Firstly, the interactions between Lanzhou and the east regions, the south boundaries, and the northwest regions of Gansu province were incompact, while the interaction between Lanzhou and the north regions, the west regions of Gansu province was compact, what＇s more, it might reach south of Ningxia Autonomous Region and east of Qinghai province. Secondly, Xining was influenced by Lanzhou intensively, while Yinchuan indifferently ; Xi＇an was important to Lanzhou; Chengdu was developmental demand of Lanzhou in the new stage; the relation between Lanzhou and Urumqi should be strengthened, which would be in favor of Lanzhou to develop international trade. Finally, economic types of interaction were summarized, which included compact relation （Lanzhou and Xining） ,awag relation （Lanzhou and Xi＇ an, Lanzhou and Yinchuan）, incompact relation （Lanzhou and Chengdu, Lanzhou and Urumchi）.
