Abstract. The interactionds betwen the biotic processes of reproduction, growth, and death and the abiotic processes which regulate temperature and water availability, and the interplay between the biotic and abiotic processes regulating N, and light availabitties are important in the dynamics of forest ecosystemsWe have developed a computer simulation that assembles a model ecosystem which links these biotic and abiotic Interactions through equations that predict decomposition processes, actual evapo-transpiration, soil water balance, nutrient uptake, growth of trees, and light penetration through the canopy. The equations and parameters are derived directly from field studies and observations of forests in easten North America, resulting in a model that can make accurate quantative predictions of biommass accumulation, N availability, soll humus development and net primary production.
