Abstract: To quantitatively study the influence of climate change on tourism industry, this paper analyzed climate change characteristics of Yantai in recent years by climatic propensity analysis. The climate comfort degree was evaluated by the climate comfort level, the correlation of climate comfort degree and tourist online attention was measured by the statistical methods. The results showed that the annual average precipitation, relative humidity and wind speed showed decreasing rends year by year, and the tendency rate was 5.77mm/(10a), 0.56%/(10 a) and 0.25 m/(s·10 a), respectively, the annual average temperature increased by a rate of 1.18℃/(10 a). As for the tourist seasons, May, June, September and October are the best tourist months in one year, April, July, August and November are suitable travel periods, however, January, February and December are not suitable for tourism. In terms of relevance, the climate comfort degree is significantly related to the tourists online attentions, with the correlation coefficient of 0.986 and the climate resilience coefficient of 0.128%. The research shows that the meteorological elements of Yantai are changing in recent years, and the climate comfort degree has a significant impact on tourism. With the climate comfort degree of Yantai changing by 1 units, the monthly degree of tourist online attention would increase or decrease by 0.128%.
