At present,big-leaf model,multilayer model,and two-leaf model of plant canopy scale are widely used,because these three models have ripe theoretical base,and successfully simulated the photosynthesis and transpiration of plant canopy.

目前植被冠层尺度的大叶模型、多层模型、二叶模型以其成熟的理论基础及对植被冠层的光合作用、蒸腾作用较为成功的模拟,得到了广泛的应用。

Results show that the photosynthesis in big-leaf model is totally 13% higher than that in two-leaf model.

以实验观测数据为基础,对棉花阳叶和阴叶光合速率、气孔导度的变化进行比较,通过双叶模型和大叶模型对冠层光合作用进行对比分析,结果表明,大叶模型的计算结果普遍高于双叶模型,总体高出13%。
