| Climate is an important factor affecting the development of tourism,It is also an important consideration for tourists to choose tourist destinations.Tourism climate comfort as a hot topic in tourism climate research,not only for the development of tourism to provide a scientific basis for the weather,but also help the tour operators to arrange activities,to help visitors choose the appropriate travel time and place.At present,China's air pollution is serious,people concerned about air quality problems."Avoiding haze" tourism is developing rapidly,the air quality of tourist destination also has become one of the most important factors when tourists choose.Chongqing is located in the subtropical inland region of the northern hemisphere,belonging to the subtropical humid monsoon climate type.While the impact of complex terrain,tourism climate comfort has difference in Chongqing.In recent years,the rapid development of tourism in Chongqing,tourism has become an important pillar industry in Chongqing.The development of tourism activities is affected by climate change in Chongqing.The study of tourism climate comfort has important significance to guide the development of tourism in different areas of Chongqing.First of all,based on the previous research,the air quality is included in the evaluation of tourism climate comfort,and the tourism climate comfort index based on temperature and humidity index,wind effect index,index of cloth loading and air quality index.Secondly,the five climatic factors related to the Chongqing's tourism climate comfort are selected: temperature,relative humidity,wind speed,sunshine,air quality.Using the daily data of temperature,wind speed,relative humidity,sunshine hours from 1985 to 2014 and the air quality data in 2016,this paper analyze the distribution characteristics of five climatic elements during the year in Chongqing.Then calculate and analyze the temperature and humidity index,wind effect index,index of cloth loading,air quality index of 15 weather stations.And calculate the tourism climate comfort index,the temporal and spatial distribution characteristics of tourism climate comfort index in Chongqing were analyzed.At the same time,we find out the number of comfortable days and the suitable period of tourism in Chongqing.Through the research,the following conclusions are obtained:(1)Temperature,relative humidity,wind speed,sunshine is an important factor affecting the tourism climate comfort in Chongqing,air quality is also an important consideration for tourists to travel.(2)From the temperature and humidity index,the best period of tourism is April to May in the northeastern of Chongqing;The best period of tourism is April and October in the southeastern of Chongqing;The best period of tourism is April and October in the trend of new urban development district in Chongqing;The most suitable tourism month is April the main city zone.From the wind effect index,the best period of tourism is January to April and October to December in the northeastern of Chongqing;The best period of tourism is January to March and December in the southeastern of

May and September to October in the southeastern of Chongqing;The best period of tourism is March to May and September to November in the trend of new urban development district in Chongqing;The most suitable tourism month is April to May and October to November the main city zone.From the air quality index,the city's annual air quality is generally located in the A level,the air quality is excellent.But air quality index of the Urban Development Zone and the main city zone is located in the B level in January to February,the air quality index is mild pollution.(3)From the whole year,the tourism climate comfort index of Chongqing has little differences.The tourism climate comfort index changes in the whole year as "M" type in Chongqing.January to April and September to November are rising;May to August and December are down.(4)The distribution of tourism climate comfort has obvious temporal and spatial characteristics in Chongqing.Throughout the year,the city's tourism climate comfortable days have small difference,but the development of the new area is slightly more than other areas.There is little difference in the number of comfortable days in the southeast of Chongqing,urban development and the main city zone,the northeast of Chongqing is the least.The less comfortable days are generally reduced from north to south,from east to west.The number of discomfort day is relatively large in Chongqing,the least is Southeast Chongqing,secondly is the northeast of Chongqing,the most is the trend of new urban development district and the main city zone.From the four seasons: Chongqing is mainly comfortable days in spring,the northeast of Chongqing is slightly higher than the trend of new urban development district and the main city zone.In summer,Chongqing is mainly comfortable days and less comfortable days.The main city zone and the trend of new urban development district are higher than the southeast of Chongqing and the northeast of Chongqing.Chongqing is mainly comfortable days in autumn,the number of days in the northeast and southeast of Chongqing are more than other two areas.Chongqing is mainly less comfortable days in winter,the number of days in the northeast and southeast of Chongqing are more than other two areas.From the perspective of changes in the year,the annual change in the number of comfort days is double peaks in Chongqing,the number of days in spring and autumn is more than the summer and the winter.(5)The city's comfortable period is March to May and October to November.However,because of the terrain factors,there are some differences.The best period of tourism is February to May and October to November the northeastern of Chongqing.The best period of tourism is March to May and October to November in the southeastern of Chongqing.The best period of tourism is March to May and October to November in the trend of new urban development district and the main city zone.(6)The number of
