摘要

The individual-based forest gap models are a potential resource in the study of forest growth responses to environmental stress acting on physiological processes. This approach is currently limited by the lack of physiological detail in the gap models and by the temporal scales separating tree physiology and the annual tree growth simulated by the gap models. We describe a general procedure that integrates process-based models of tree physiology with forest gap models. The procedure involves (1) a link between a physiological model and a gap model provided by the simulation of annual wood production (AWP), (2) a factorial execution of a physiological model to generate AWP, (3) a response-surface model describing the relationship between AWP and driving variables appropriate to the annual time scale of a gap model, and (4) a revised gap model that includes a rescaled physiological model. The modified gap model can be used to simulate the impact of environmental stress on forest growth and succession. 18 refs., 2 figs. (ERA citation 14:004265)
