Abstract: Based on the meteorological observation and ecological quality monitoring data of Lushan from 1981 to 2020, the climate comfort of human settlements in the past 40 years and each month was calculated, and the tourism climate suitability was evaluated combined with the normalized difference vegetation index ( NDVI ). The results showed that the climate comfortable period of living environment in Lushan County is from April to November, and the negative oxygen ion level was high. In the past 40 years, the temperature showed an increasing trend, while the relative humidity and wind speed showed a decreasing trend. Temperature and humidity index showed an upward trend, wind efficiency index showed a downward trend, the comfort of living environment increased, NDVI increased slowly. The temperature and humidity index and wind efficiency index were positively correlated with the average temperature, and negatively correlated with the relative humidity, indicating that the increase of temperature and the decrease of relative humidity are the main factors affecting the increase of climate comfort.
