| 摘 要： | 依据彭曼-蒙蒂思(Penman-Monteith)模式对田间冬小麦蒸腾量的计算方法进行了研究,对计算模式中包含的两个主要参数进行了详细的分析与讨论.提出了冬小麦冠层截留的净辐射(Rn')和冠层整体气孔阻力(r8T)的经验表达式,对模式的计算精度作了检验,并分析了缺水条件下冬小麦实际蒸腾量与充分供水条件下潜在蒸腾量的关系.

| Abstract: | Based on the Penman-Monteith Model(PMM), a method for calculating winter wheat transpiration in the field condition is established, and two main parameters involved in the PMM are anatysed. The emperical equations of net radiation intercepted by canopy (Rn') and total canopy leaf resistance (r8T) are presented, and their precision is checked. The relation between the actual transpiration in the deficient water condition and potential transpiration in the safficient water condition is analysed. |

| Keywords: | transpiration net radiation stomatic resistance |
