中文摘要：

结合ArcGIS软件的核密度、反距离加权等方法，揭示了兰州市主城区酒店的空间分布格局及其影响因素．研究表明：整体上，兰州市主城区酒店分布极不均衡，城关区最多（占68．3％），西固区最少（占6．4％）；空间上呈“东密西疏”和“多中心组团”的分布特征；类型上四星级酒店的空间分布差异最大，二星级以下及经济型最小．具体而言，五星级酒店呈点状分布、四星级酒店则以簇状分布为主、三星级酒店呈串珠状分布、二星级以下及经济型酒店具有明显的片状分布特征：城市形态、交通网络、土地价格、功能分区是影响酒店空间布局的主要因素．

英文摘要：

： Combining ArcGIS software, nuclear density and inverse distance weighting methods, the spa- tial distribution patterns and main factors of Lanzhou＇s hotels were revealed. The results showed that dis- tribution of hotels is extremely uneven, concentrated mostly in Chengguan District of the city （68.3%）, with only 6.4% in Xigu District. The space pattern is ＂dense in the east and sparse in the west＂ with a ＂multi-center＂; as for the types, four-star hotels have the largest space distribution difference, two-star and economy hotels of minimum space distribution difference. Specifically, five-star hotels are distribut- ed in points, four-star hotels mainly in clusters, three-star ones in chained-beads, the following and two- star and economy ones in obvious patchy distribution. The factors influencing hotel distribution include the urban configuration, transportation networks, land prices and urban district functions.
