摘要
Air and soil temperatures were observed in and out of broadleaved P.koriaensis forest (average height 25m) at Changbai Mountain in July,2000.The results showed that there was a very obvious difference between temperatures in and out of forest and both of them showed diurnal variation.Air temperature in the forest at 2m height was always lower in daytime and higher at nighttime than that in the open air.Air temperature at height of 22m in the forest was higher than that at 2m.The difference of air and soil temperature at the two sites in clear day was larger than that in cloudy day,and the latter was larger than that in overcastday.Reasons were also explained.
