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
Based on the observation data of temperature on the southwest edge of Xishuangbanna rubber plantation in the tropical quiet zone of China in January, the thermal characteristics and the temporal and spatial variation of the marginal zone in daytime were discussed. The results showed that there was obvious thermal effect on the forest margin, The influence depth can reach about 13m in the forest, the ground temperature reaches the highest at 4.5m outside the forest, and the temperature appears most at the forest margin (0m). The heat transport near the forest edge has great difference in value and direction The heat is transported from the ground to the air; in the afternoon, in the forest, contrary to the forest, the heat is transported downward from the upper (canopy) to the ground (ground); while there are different locations near the forest edge with large differences between different times
