What is the best way to represent surface conductance for a range of vegetated sites

摘要: Surface conductance Gs is a significant parameter for indicating the evaporative and photosynthetic properties of vegetated surface. When comparing values between different observation sites, some studies have used Gsmax others Ĝsmax (where maximum value measured during measurement period, obtained with vapour pressure deficit (VPD) ≥ 1·0 kPa period). In this study, we demonstrate clear justification using instead when sites. We examined whether both lead to same conclusions in classifying Komatsu (2003b) [Hydrological Processes 17: 2503–2512] reported relationship canopy height h coniferous forests projected leaf area index (LAI) 3·0. not only but also LAI 3·0. Both decreased increasing h. However, was less well defined than because biased data. Consequently, conclude that more appropriate represent sites vegetation. Copyright © 2007 John Wiley & Sons, Ltd.
