| 摘 要： | 利用西双版纳干季(12月、4月)次生林林窗的温度观测资料，探讨了晴天林窗4方位的气温的空气变化特征。由于林窗的不同位置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外。这势必造成林窗不同区域热量传输的不同，形成林窗小气候的差异。其结果可为进一步研究森林林窗小气候及有关生态学现象提供基础。

| Abstract: | Temperature measurements at the canopy gap of a secondary forest were conducted in Xishuangbanna,Yunnan in dry season.The results showed that there was a significantly thermal effect at the gap,and the maximum air temperature and the diurnal range of air temperature in the gap was quite different.The extreme value was on the east edge of gap,and it may be a reason to form the special microclimate in the gap.The results supplied a basis in further studying canopy gap microclimate and the relevant ecological phenomena. |
