摘　　要：在"旅游网站信息流距离衰减形态描述与集中度计算"[1]一文的基础上,从旅游网站性质的角度对旅游网站信息流距离衰减形态与集中性的差异进行指数衰减模型的拟合分析,并应用Zipf定律检验其特征,发现:1)不同性质的旅游网站信息流距离衰减形态存在差异,旅游主管部门网站、旅游企业网站、旅游目的地网站的信息流距离衰减形态分别表现出非常符合指数衰减模型、基本符合指数衰减模型、不符合指数衰减模型特征。2)不同性质的旅游网站信息流距离衰减的集中性存在差异,分别表现出具有明显的本地集中性特征、兼有本地集中性和经济集中性特征、具有明显的经济集中性特征。3)分维值多在0.5左右说明了旅游网站信息流距离衰减集中性较强,分维值的差异说明了不同性质旅游网站信息流距离衰减集中性存在差异。旅游网站信息流的位序-规模均符合Zipf定律,其首位省市均存在于网站所在地或者周边省市,其位序-规模的前四位总体为经济发达省市,说明了旅游网站信息流距离衰减具有本地和经济集中性。4)对旅游网站信息流距离衰减集中性的Zipf检验,证实了空间距离集中性特征的普遍意义。Based on the paper of ＂Description of Distance Decay Patterns of Tourism Websites Information Flow and Calculation of Its Concentration＂,the exponential decay model was used to analyze tourism website information flow distance decay form and concentration differences from the angle of tourism website properties,meanwhile Zipf Law was applied to examine its concentration characteristics.The results are as follows：1） The tourism websites with different nature have different information flow distance decay forms.Tourism website information flow distance decay forms have shown different characteristics respectively in tourism department website,tourism enterprise website and tourism destination website,which is the tourism website information flow distance decay is very accord with exponential decay model,basically accord with exponential decay model and do not fit the exponential decay model.2） The concentration of information flow distance decay of the tourism website with different nature is difference.The tourism department website information flow distance decay has obvious local concentration characteristics.Tourism enterprise website information flow distance decay has both local concentration and economic concentration characteristics.Tourism destination website information flow distance decay has obvious economic concentration characteristics.3） Most fractal dimension value around 0.5 means that the concentration of tourism website information flow distance decay is strong.The difference of fractal dimension value shows that the concentration of tourism website information flow distance decay is different in different nature tourism websites.The sequence-scale of tourism website information flow is accord with Zipf Law.Its first province is website location province or provinces around.The first four provinces for sequence-scale are developed provinces which can explain tourism website information flow distance decay having both local concentration and economic concentration characteristics.4）
