| 摘 要： | 利用西双版干热季次生林林窗的温度观测资料，探讨了林窗４方位的气温时空变化特征。由于林窗不同区域所受太阳辐射的影响不同，加之林缘热力效应的综合作用，林窗中存在明显的气温差异，特别是最高气温差异显著；气温最高值和气温日较差最大值不在林窗中央而出现在林窗东侧林缘树冠垂线处。

| Abstract: | Temperature measurements at the secondary forest canopy gap were conducted in Xishuangbanna, Yunnan in April, 1998 (dry hot season). On the basis of this measurements, the maximum and minimum temperature characteristics and their time space variations on 4 azimuth in the secondary forest canopy gap were discussed. The results showed that there was a significantly thermal effect at the gap, and the maximum temperature and the diurnal range of air temperature in the gap was quite different, the extreme value was on the east edge of gap, which may be a reason to form the gap microclimate. The results supplied a basis in further studying canopy gap microclimate and the relevant ecological phenomena. |
