温度作为影响植物生产力和植物分布的重要因素之一，在很大程度上也影响着植物的生理生态特性。本文利用两台高分辨率热像仪（P25， Flir系统，Wilsonville， OR， USA）对中国西南地区一个36 m高热带雨林和28种树种的冠层叶温分布进行了研究。优势树种tomentosa的叶温最高（31.8℃），比优势树种Mezzettipsis creaghii的叶温（21.6℃）高10.2℃。平均叶对空气温差（Tc-Ta）以毛竹最高（6.4 K），次之为白头藤（6.1 K），毛竹最低（1.9K）。叶片小、气孔导度大的树种（Tc-Ta）对气候因子的敏感性较低。叶片大小和气孔导度共同决定了气候变化对不同树种（Tc-Ta）的影响。我们的研究表明，热带雨林地区的树种组成对气候具有重要意义。
As one of the important factors affecting plant productivity and plant distribution, temperature also affects the physiological and ecological characteristics of plants to a large extent. We report canopy leaf temperature distribution over a 36 m tall primary tropical rain forest and samplings of 28 tree species in SW China by means of two high resolution thermal cameras (P25, Flir systems, Wilsonville, OR, USA). The leaf temperature of dominant tree Species Pometia tomentosa was the highest (31.8 °C), 10.2 °C higher than that of tree species Mezzettipsis creaghii (21.6 °C). The mean leaf to air temperature difference (Tc–Ta) of Pometia tomentosa was the highest (6.4 K), the second highest was Barringtonia pendula (6.1 K), and Mezzettipsis creaghii had the lowest (Tc–Ta) (1.9K). (Tc–Ta) of tree species with smaller leaves and larger stomatal conductance was lowly sensitive to climate factors. Leaf size and stomatal conductance together decided the effect of climate change to (Tc–Ta) of the different tree species. We have shown that the composition of tree species in tropical rain forest areas is important to the climate through our research.
