Study on Change Characteristics of Environmental Factors and Climate Comfort Degree in the Monkey King Valley Forest Therapy Base in Wencheng County

In order to better grasp its disciplines of environmental factors and climate comfort degree in the Monkey King Valley forest therapy base in the Wencheng County, from Sep. of 2017 to Aug. of 2018, the environmental factors such as air temperature, humidity, wind speed and PM_2.5 concentration were monitored in situ by ZK-FO system. The results showed that the seasonal variation of environmental factors was only obvious in temperature. The temperature and humidity were obvious in the daily variation, while their variation trends were different. The wind speed and PM_2.5 concentration had no significant daily variation. The climate comfort degree showed obvious monthly change. From Apr. to Oct., it was lower than 6.95 which meant comfortable. There was no uniform rule in the daily change of climate comfort degree. The comfort degree of the whole day in summer was the lowest as the average value was 3.03, in addition that the change range of whole day was tiny.
