Abstract:
In view of the current situation that air pollution and severe haze weather frequently hinder the further development of the tourist industry in tourist cities in China, the monthly mean air quality comprehensive index (AQCI)at 280 sites of 31 major tourist cities in China from 2013 to 2019 was used to study the spatial and temporal distribution characteristics and changing trends of air quality comprehensive index by means of mean statistics and trend regression.The results showed that: （1） AQCI is higher in winter, lower in summer, and centered in spring and autumn. The mean value of AQCI in northern inland areas is higher than that in southern areas and coastal areas.（2） According to the AQCI values of each station, more than 80% of the air quality in spring and autumn is mildly or severely polluted. In winter, more than 60% of the air quality is moderately or severely polluted. More than 90% is good in summer.（3） From the perspective of trends, the number of sites in the downward trend of AQCI exceeds that in the upward trend.In recent years, the air quality is improving in most tourist cities in China.（4） Suitable cities for longterm tourism are Haikou, Fuzhou, Lhasa, Guiyang and Kunming. Beijing, Shijiazhuang, Taiyuan, Zhengzhou and Tianjin have one suitable month for tourism.（5） Air pollution has a direct or indirect impact on the tourism resources, traffic, tourism brand construction, tourism market development and tourists of tourist cities, and finally affects the benefits of tourism in the region from economic, social and ecological aspects.
