摘要/Abstract

摘要： 利用西双版纳雾凉季和干热季热带次生林林窗的小气候垂直观测资料,探讨了昼间林窗区域树表温、气温、水汽压及相对湿度的时空分布和变化规律.指出在林窗区域,林窗边缘不仅具有显著的热力效应,同样具有明显的水汽效应.并由此构成了林窗区域立体空间的环境异质性.其结果对深入探讨林窗区域的热量、水汽传输,小气候的形成机制,生物多样性和更新等问题均具有重要意义.

Abstract: Based on the data obtained from vertical gradient measurements of microclimatic elements of canopy gap in tropical secondary forest of Xishuangbanna in fog cool and dry hot season,the daytime characteristics of temporal spatial distribution and variation of trunk surface temperature,air temperature,water vapor pressure and relative humidity in canopy gap were discussed. The data showed that gap edge had not only a remarkable thermal effect,but also a significant water vapor effect. These effects resulted in environmental heterogeneity in canopy gap. The results provided a basis for further studying heat and water vapor transport,microclimatic formation,biodiversity,and forest succession in canopy gap.
