运用ArcGIS9．2软件，结合ESDA方法对南京市星级酒店空间可达性格局进行分析，结果表明：南京市星级酒店空间可达性整体较好，在地域分布上呈以酒店为中心的距离衰减规律，而且等级愈高的酒店可达性愈差。其中二、三星级酒店的空间可达性较好且较相似，而四、五星级酒店可达性也较相似但较差；基于乡镇街道为统计单元的二、三星级酒店可达性总体集聚程度相当且较低，而四、五星级酒店总体集聚程度相当且较高；可达性热点区与冷点区呈现以主城区为中心的圈层结构，其中热点区主要分布在主城区，而冷点区分布在南京市域边缘区域；最后将星级酒店可达性格局的影响因素归纳为酒店分布、行政单元大小、交通基础设施、旅游资源和经济条件等，其中前3个为直接原因，后2个是间接原因。

In order to make a quantitative analysis about spatial pattern of accessibility about star-rated hotels in Nanjing City, the software of ArcGIS 9.2 was adopted and the method of ESDA was used to analyze it by indexes such as Moran＇ s I and Getis-Ord Gff. The result showed that the overall accessibility of different star-rated hotels in Nan- jing City was fairly good basically. However, as to the overall distribution, the accessibility diffusion graph followed the rules of distance decay, which led to a regional layered spatial structure. What was more, the higher the level of star-rated hotels they were, the worse the overall accessibility was. On the whole, the overall accessibility of two-star hotels and three-star hotels was much better and similar. The overall accessibility of four-star hotels and five-star hotels was similar too but relatively bad. At township （neighborhood） level, the estimated values of Moran＇ s I were all positive numbers using analysis of spatial asso- ciation. All the test results indicate that the estimated values of Moran＇ s I about two, three-star hotels showed weak positive correlation, while the estimated values of Moran＇ s I about four, five-star hotels indicated more significant positive correlation, twice as high as two, three-star hotels. The accessibility diffusion graph of hot spot regions and cold spot regions took on a la- ver structure which taking the main urban area of Nanjing, in which the hot spot regions were mainly distributed, as the cen- ter, while the cold spot regions were distributed in border districts of Nanjing City. And finally, on the basis of the above re- suits, some factors, which impacted the accessibility pattern of Nanjing City, such as the distribution of star-rated hotels, the size of administrative unit, transportation infrastructure, tourism resources and economic conditions, were summed up in the paper, and the former three were the immediate causes , the latter two factors were indirect causes.
