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) The Zipf examination of tourism website information flow distance decay concentration has confirmed the general significance of space distance concentration characteristics.
