Influence of stand parameters on evaporation in forests

Based on individual published investigations an attempt is made to systematize the evaporation in forest stands in dependence on stand parameters only. Based on the data available for this paper transpiration, interception and evapotranspiration can be considered as terms of evaporation and tree genus, age of stand, stand density and partially stocking degree as stand parameters. Tree genus includes mainly spruce, pine, beech and oak. The results of this analysis show no functional dependencies of general validity but only some slight tendencies. The reasons responsible for this are discussed.
