The universality and the diversity on Water/Energy/Carbon exchanges of forests in East Asia

通过观测和模拟，研究了东亚温带森林从热带森林到北方森林的水分、能量和碳(W/E/C)交换。高纬度地区的森林环境比低纬度地区更为恶劣，尤其是在冬季。热带、温带和北温带树木个体的响应不同，但林分尺度的响应相当于环境条件与森林电导率之间的几条势线。这几个模型基本可以描述W/E/C循环，但在热带森林中还需要增加土壤深层的水分供应。

The water, energy and carbon(W/E/C) exchanges from tropical to boreal forests through temperate forests in the Eastern Asia are examined from the tree levels to the forest levels with the observations and modelings. The forests environments, especially in winter, are severer in the high latitudes than in the low latitudes. And the responses of individual trees in the tropic, the temperate and the boreal zones are different each others, but those of stands scales are equal to several potential lines between the environment conditions and the conductance of the forests. The several models can be possible to represent the W/E/C cycles basically, but the soil water supply in the deeper parts of the soil layers is needed to add in the tropical forests.
