The "yes" or "no"(1 or 0) of distribution of reptiles in Guangdong Province were regarded as two-state character. The relative coefficient was taken for the similar degree of reptiles in every two zoogeographical provinces. The cluster analysis was taken by group average method. The characteristics of geographical distribution and the comparison between the result of cluster analysis and the geographical distribution of reptiles in Guangdong Province are discussed.

No.2 part includes No.4 and No.5 chapter. In No.4 chapter the paper calculates centrality indexes of the tourism destinations of 13 cities along Silk Road in Gansu. In No.5 chapter the paper analyzes these indexes with Hierarchical Cluster of SPSS 13.0, and adds up ancient ruins of these regions. Abasing centrality indexes of the tourism destinations, the result of Hierarchical Cluster and the concentration ancient ruins of these regions, the paper determines that Lanzhou City and Dunhuang City are No.1 grade tourism central cities, Jiayuguan City and Tianshui City are No.2 grade tourism central cities, Hezuo City Prefecture, Zhangye City and Wuwei City are No.3 grade tourism central cities, Pingliang City, Jingchang City and Linxia City Prefecture are No.4 grade tourism central cities. No.3 part includes No.6 and No.7 chapter.

第二部分(4-5)。首先提出了旅游中心性指数概念，设置旅游中心性指标体系，计算各&节点城市&的旅游地中心性指数，并对这些指数进行聚类分析，然后统计&节点城市&丝路文化遗存旅游资源的集中度，最后采用定性和定量相结合的方法，将丝绸之路甘肃段&节点城市&的中心性指数、聚类分析的结果和丝路文化遗存旅游资源的集中度结合起来进行分析，确定出兰州市和敦煌市为一级旅游中心城市，嘉峪关市+肃州区、天水市为二级旅游中心城市，合作市、张掖市和武威市为三级旅游中心城市，平凉市、金昌市和临夏市为四级旅游中心城市。
