摘要
The correspondence between multiyear mean values of annual transpiration values derived with the Penman-Monteith methods using the coefficient of transpiration efficiency is demonstrated. It is suggested to take into account climate peculiarities in the region when estimating the transpiration with the Penman-Monteith method. In the mid-taiga sub-zone that is characterized by high moisture content, the stomatal resistance (conductance) of the leaf apparatus, when calculating the diurnal transpiration, can be taken as constant, independent of the meteorological conditions.
