Analysis on the Air Temperature and Relative Humidity Change of Primitive Forest Region of Great Khingan in Inner Mongolian

Using the air temperatue and humidity data of primitive forest region of great Khingan in Inner Mongolian in 2006 years,this article analyzed the air temperature and humidity change of this forest region. The results showed that： the diurnal and annual variation of air temperature in forest region showed cosine curve type. The daily and annual change extremum of air humidity in dif-ferent height was different, the maximum value of monthly average temperature was in July, the minimum value was in January, the daily and annual range was decreased with the height increase. The diurnal and annual variation of relative air humidity in forest re-gion showed sine curve type, the maximum value of daily relative air humidity was in 04 oclock, the value was 79%, the minimum value was in 14 oclock, the value was 10%. The maximum value of annual relative air humidity was in June, the value was 81%, the minimum value was May, the value was 53%.
