中文摘要：

以旅游空间结构理论为基点,构建了旅游中心性城市评价指标.应用因子分析法,对甘肃省14个市州的旅游中心性进行了测定.结果显示,兰州、酒泉、天水是甘肃旅游发展的三个核心城市.借助引力模型,分析了甘肃省旅游空间内部的旅游经济联系度和强度,发现旅游经济联系量集中在少数几个城市.在此基础上,把甘肃省的旅游空间结构构建为丝绸之路旅游带、大兰州旅游经济圈、天水旅游经济圈、敦煌旅游经济圈的“一带三圈”.

英文摘要：

Based on tourism spatial structure theory, this paper built a tourist center city evaluation and factor analysis which was used to analyze the Gansu Province fourteen cities. The results showed that Lanzhou, Jiuquan and Tianshui were the there core cities. Subsequently, using the gravity model, this paper analyzed the strength and the direction of tourism economic ties and intensity inside the tourism system of Gansu Province, and found that the tourism economic ties concentrated in a few cities. On this basis, it was possible to build the tourism spatial structure of Gansu Province into ＂one development zone, three circles＂. That were the silk road tourist belt,big Lanzhou economic circle, Tianshui economic circle, Dunhuang tourism economic circle.
