Résumé

A simple regression model for calculating annual actual evapotranspiration (ET) andpotential evapotranspiration (PET), as well as annual transpiration (TR) of mature borealforests grown in the European part of Russia in the Holocene using paleoclimatic andpaleobotanical data (air temperature, precipitation, forest species compositions) ispresented. The model is based on nonlinear approximations of annual values of ET, TR andPET obtained by the LevenbergMarquardt method using the results of numericalsimulations of ET, TR and PET provided by a process-based Mixfor-SVAT model forforests with different species compositions under various thermal and moisteningconditions. The results of ET, TR and PET reconstructions for the Holocene showlarge variability and high correlation with the air temperature pattern. Minimalvalues of ET and PET are obtained for the Younger Dryas cold phase (11.010.0 14CkyrBP) when ET varied between 320 and 370mmyr 1 and PET variedbetween 410 and 480mmyr 1. During the Late Atlantic periods of the Holocene (4.55.114CkyrBP), ET and PET reached maximal values (ET: 430450mmyr 1 and PET:550570mmyr 1).
