The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.

用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测，重点分析了23m、39m两层高度的观测结果，同时把观测期分为春季和冬季两个不同时间段作了对比：结果表明，不管冬季还是春季，39m高度所测的总通量值和夜间通量值都要小于23m的观测值，这种通量差别表明：23m高度的观测结果更接近当地生态系统与大气之间的通量交换值，在此种生态类型条件下用涡度相关法测碳通量时，在23m、39m两层高度之间仍然存在大气平流现象；该试验区植被在冬季仍然可以进行光合作用，而且光合作用所吸收的CO2大于呼吸作用所排放的CO2，因此该种生态系统在冬季仍表现为碳汇；春季的碳通量值为冬季的2倍以上。
