冠层温度是冠层能量平衡的结果,由气候条件、植物结构和植物控制的蒸腾作用驱动。在这里,我们评估了中国西南部西双版纳橡胶园 (RP) 和热带雨林 (TR) 的冠层温度。每个地点都安装了红外温度传感器来测量冠层温度。在旱季,RP 和 TR 中冠层温度 (Tc) 和空气温度 (Ta) 之间的最大差异 (Tc – Ta) 分别为 2.6 和 0.1 K。在雨季,RP和TR的最大(Tc - Ta)值分别为1.0和-1.1 K。两种森林之间存在一致的差异,全年RP的(Tc - Ta)值高于TR。 Tc 的红外测量可用于计算这两个森林的冠层气孔导度。随着直接辐射的增加,RP 中的 (Tc - Ta) 在三个 gc 水平上的差异大于 TR 中的差异,表明 RP 中 (Tc - Ta) 的变化对气孔关闭程度相对敏感。
Canopy temperature is a result of the canopy energy.balance and is driven by climate conditions, plant architecture,.and plant-controlled transpiration. Here, we evaluated.canopy temperature in a rubber plantation (RP) and tropical.rainforest (TR) in Xishuangbanna, southwestern China. An.infrared temperature sensor was installed at each site to measure.canopy temperature. In the dry season, the maximum.differences (Tc − Ta) between canopy temperature (Tc) and.air temperature (Ta) in the RP and TR were 2.6 and 0.1 K,.respectively. In the rainy season, the maximum (Tc − Ta).values in the RP and TR were 1.0 and −1.1 K, respectively..There were consistent differences between the two forests,.with the RP having higher (Tc − Ta) than the TR throughout.the entire year. Infrared measurements of Tc can be used to.calculate canopy stomatal conductance in both forests. The.difference in (Tc − Ta) at three gc levels with increasing direct.radiation in the RP was larger than in the TR, indicating that.change in (Tc − Ta) in the RP was relatively sensitive to the.degree of stomatal closure.
