Analysis of the climate comfort for summer tourism in Bifeng Gorge,Yaan city of Sichuan province
Based on the daily temperature,precipitation,wind speed,relative humidity,and negative oxygen ion concentration observation data in Bifeng Gorge scenic area(BGSA)and the daily sunshine observation data of Yaan meteorological observatory station closest to BGSA,this paper constructed a tourism meteorological compre-hensive index(TMCI)using temperature-humidity index(I),wind efficiency index(K),human body comfort index(HBCI),and air freshness index(negative oxygen ion concentration,N).The monthly and seasonal charac-teristics of the main tourism climate resources and tourism indices in BGSA were explored.The impacts of extreme weather and meteorological geological disasters on summer tourism in BGSA were also analyzed.The results show that the meteorological elements such as temperature,precipitation,humidity,wind speed,sunshine,and ultraviolet intensity in BGSA are suitable for summer tourism.The temperature-humidity index,wind efficiency index,HBCI,and TMCI from May to September in BGSA are suitable or very suitable for summer tourism.The negative oxygen ion concentration level in BGSA is above level I for 92.4%of the year,making it very suitable for tourism.The risk of extreme weather and meteorological geological disasters in BGSA is not significant throughout the year,and the impact of natural disasters on BGSA summer tourism is relatively small.In conclusion,BGSA is a great place for summer tourism.
