Abstract

A multilayer, one-dimensional model is used to explore the processes regulating photosynthesis in two forest canopies with contrasting structural and physiological properties. An evergreen coniferous forest dominated by Dacrydium, growing at a site with very low nutrient availability in New Zealand, is compared with a deciduous mixed Quercus forest, growing at a site with high nitrogen inputs from atmospheric deposition at almost the same latitude in the north-eastern USA. The canopy model integrates radiative transfer, energy balance, evaporation and photosynthesis, coupled with stomatal conductance, in 20 layers through the canopy and is combined with a simple water-balance model to introduce the effects of seasonal root-zone water balance and alllow the estimation of net annual carbon uptake. Estimates of the vertical distribution of foliage area and measurements of physiological parameters for the two sites were made for the model.
