Evaluating the models of stomatal conductance response to humidity in a tropical rain forest of Xishuangbanna, southwest China

摘要: The ecosystem-level fluxes of water vapour and carbon dioxide were measured from 2003 to 2006 at a tropical rain forest in Xishuangbanna, southwest China, using the eddy covariance (EC) technique. These flux measurements allowed canopy-level evaluation stomatal conductance (g) response humidity models. results showed that both BWB model Leuning discussed here underestimated g high overestimated mid-to-low range humidity. In contrast, Wang models (model-ha model-Da) perfectly described relationship comparison also demonstrated consistency over all observation years. good performance model-ha model-Da indicated responds more sensitively deficit or pressure than relative itself canopy level.
