Abstract

Abstract: Temperature measurements at the secondary forest canopy gap were conducted in Xishuangbanna, Yunnan in fog-cool season and dry-hot season. On the basis of this measurements, the air temperature characteristics and their spatial variations in different seasons in the secondary forest canopy gap were discussed. The findings showed that there was a significant thermal effect at the gap.The effect of sunshine on the air temperature in the gap was quite different, the extreme value was on the eastern edge of gap, which may be a reason to form the gap microclimate. The results supplied a basis on further study canopy gap microclimate and the relevant ecological phenomena.
