Abstract：Using meteorological observation data at Beiji Village meteorological observatory from 1961 to 2021,this study analyzed the climate characteristics in Beiji Village,divided the climate sea-sons,calculated the climate comfort index,analyzed the variations of climate comfort,discussed the im-pact of climate change on tourism in Beiji Village,and provided a theoretical basis for understanding sci-entific issues such as climate change in high latitude areas and its impact on ecotourism.The results showed that the average annual temperature in Beiji Village was-3.3℃,with the highest average tem-perature of 19.4℃and the lowest average temperature of-28.3℃,and the temperature difference was 47.7℃.The annual average precipitation in Beiji Village was 457.4 mm,with precipitation days of 115.9 days,precipitation intensity of 3.3 mm/d,and average maximum daily precipitation of 41.9 mm.Beiji Village was classified as a perennial summer-less area,while spring start date was May 16th and the spring length was 58 days;the start date of autumn was July 13th,and the length of autumn was 58 days;the winter started on September 9th and lasted for 249 days.However,since the 1990s,33%of the years in Beiji Village had a summer,while the longest duration was 18 days.Beiji Village was shifting from"long winter without a summer"to"long winter with a summer".The annual average climate comfort level of Beiji Village was the cool level(level 7).Winter climate comfort level was the cold level(level 8).Non-winter climate comfort level was the comfortable level(level 5).Under the background of cli-mate warming,the comfort level of Beiji Village changed.Before 1982,the winter climate comfort level was the severe cold level(level 9),and after 1983,it was mainly the cold level(level 8).Before 1986,the non-winter climate comfort level was the slightly cool level(level 6),and after 1986,the comfort level was mainly the comfortable level(level 5).
