Abstract: Based on the meteorological data of Liuzhou national basic meteorological station from 1961 to 2020, the monthly and annual human settlement climate comfort in Liuzhou in the past 60 years was evaluated and the change trend was analyzed with the temperature-humidity index and the wind efficiency index as the evaluation indexes of human settlement climate comfort. The results showed that the temperature and humidity index and wind efficiency index increased first and then decreased from January to December. The annual changes of temperature and humidity index and wind efficiency index from January to December were not obvious. The final evaluation was that January, February and December were cold, March was cold, April, May and September to November were comfortable, and June to August was hot. In the past 60 years, the temperature and humidity index was in the comfortable range and showed an indigenous upward trend, and there were 4-year and 8-year periodic changes. The wind effect index was in the comfortable range from 1961 to 2017, and was in the cold range from 2018 to 2020. There was no obvious change trend and periodic variation.
