Forest categorization according to dry‐canopy evaporation rates in the growing season: comparison of the Priestley–Taylor coefficient values from various observation sites

摘要: Summarizing observed dry-canopy evaporation (hereafter, evaporation) data from earlier papers, we developed a scheme for forest categorization according to rates in the growing season. Evaporation were represented by Priestley–Taylor coefficient α calculated daytime. We examined relationships between properties (e.g. climatic regions, leaf types) and values. obtained 67 sites papers. Based on these data, found (i) clear difference values broad-leaved coniferous forests, (ii) greater variation individual forests than (iii) relationship canopy height forests. These three results supported surface conductance summarized concluded that should be primarily classified into further height. This classification is applicable only with projected area index (LAI) ≥3·0. Regardless of this LAI limitation, will useful because many satisfy limitation. This paper shows valuable following two respects. First, explicitly Although would have been implicitly recognized, has not shown based adequate amounts data. Second, it classifying as important type (broad-leaved or coniferous). studies recognized effect rates, significant compared effects other factors previously shown.
