| 摘 要： | 本文通过桤柏混交林气体交换测定研究了能量代谢基本过程。结果表明：桤柏混交林吸收的太阳辐射能大部分损耗子蒸腾作用中，桤木和柏木用于生长呼吸中损耗的能量最多．其中桤木南面时则用于维持呼吸中损耗能量最多，其能量固定建立在内部节律基础上，柏木能量积累大于桤木．

| Abstract: | The basic process of enersy supersession was studied by means of the determination of gasexchange in mixed alder and cyprus forests.The results have shown that most of the solar radiantenergy absorbed by the ined fored iS lost in evapo-transpiration.The most energy loss is used forthe growth respiration of alder and cypress trees. |
