Research On The Spatial And Temporal Variation Of Domestic Summer Tourism Demand Based On Climate Conditions

In recent decades,countries all over the world have been paying attention to the phenomenon of global climate warming.As an important natural resource and tourism resource,climatic conditions are undoubtedly one of the key elements that cannot be ignored in the process of tourism development.In summer,domestic areas generally have high temperatures,and some areas are extremely hot and extremely uncomfortable.This has gradually formed what is now a "fire-furnace city",while the demand for summer tourism by domestic residents has grown rapidly.In order to study the temporal and spatial distribution pattern and distribution characteristics of summer tourism demand from the perspective of climatic conditions,this paper uses the domestic meteorological data from June to August in the past 20 years as the data source based on the research of predecessor scholars,using analytic hierarchy process,Arc Gis geographic space Analytical method,questionnaire survey method and field survey method,try to establish a comprehensive climate comfort index model,through analysis and research,the following conclusions are obtained:(1)Different climate elements have different spatial distribution characteristics.In terms of average temperature,due to latitude differences and underlying surface differences,the average temperature values in China's coastal regions,central regions,and Xinjiang are generally higher than other regions;in terms of average humidity,it is mainly due to the warmth and heat carried by the southeast monsoon.The influence of water vapor presents a decreasing trend from southeast to northwest.In terms of average wind speed,affected by terrain and human activities,the overall average wind speed in other parts of the country is significantly higher than that in the southwestern region;the duration of sunshine The above is mainly due to the change of the direct sun point,due to the difference in latitude and topography,the sunshine duration in the northern part of China is significantly longer than that in the southern area.(2)According to the comprehensive climate comfort analysis,(1)In terms of spatial distribution,from the perspective of temperature and humidity index,most areas of my country belong to the hotter climate zone,while the southern region has been in a state of hot,muggy and extremely sultry for a long time.Relatively cool and comfortable.From the perspective of wind efficiency index,at the junction of Hunan,Jiangxi,and Hubei provinces,Guangdong,Guangdong and Jiangsu and Zhejiang regions are extremely sultry,while coastal and central regions are generally hotter,while other regions are relatively cool and comfortable.From the perspective of the comprehensive climate comfort index(Figure 4.3d),the north of the yellow difference line is the climate discomfort zone,and the south is the climate comfort zone.(2)In terms of time distribution,the temperature and humidity index,the wind efficiency index and the comprehensive climate comfort index all began to decrease in June,the lowest value appeared in July,and the trend of change gradually increased in August.(3)According to the survey,hot weather is the main motivation for summer travel.Subsequently,combined with the data of the number of consecutive high-temperature weather days and the average daily temperature difference in the past 10 years,a spatio-temporal distribution map of comfort in high-temperature weather(Figure 5.8)was obtained.Among them,in terms of space,the yellow line of difference between Hebei and Yunnan is the boundary,the north of the curve is the uncomfortable zone,and the south of the curve is the comfortable zone.Among them,the region with the lowest domestic comfort level,or the region with the strongest demand for summer tourism,is the discomfort zone enclosed by the middle and lower reaches of the Yangtze River,followed by other coastal regions and central regions.(2)In terms of time,the demand for summer tourism initially occurred in June,with a peak in July,and began to show a gradual weakening trend in August.
