摘要： 利用我国热带静风区——西双版纳橡胶林西南向边缘 1月的温度观测资料,探讨了昼间林缘区域热力特征及时空变化规律.结果表明,在林缘存在着明显的热力效应;对地面温度的影响深度可至林内约 13m处,地面温度在林外 4.5m处达最高,气温则在林缘(0m)出现最大;林缘附近热量的输送在数值和方向上存在较大差异,即林外热量从地面向空中输送;林内在午后与林外相反,热量由上 (林冠)向下 (地面)输送;林缘附近则在不同地点、不同时刻之间存在较大差异.

Abstract: The temperature measurement at south west-facing edge of a rubber forest was conducted in a calm tropical region of Xishuangbanna,Yunnan,China in January 1998,and the daytime thermal characteristics and their time-space variations nearby the edge of the rubber forest were discussed.There was an obviously thermal effect at forest edge.The depth of edge influence on soil surface temperature was up to 13m from the edge into the forest.Soil surface temperature reached its highest at 4.5 m outside the forest.The highest air temperature occurred at 0 m of the edge.The heat transfer nearby the edge was quite different in number and in direction.Outside the forest,the heat was transferred from ground to air on almost daytime,while at interior of forest,was opposite after the noon.The heat was transferred from the rubber canopy to the ground.At the forest edge,such variation was complex,depended mainly on location and time.
