Towards an analytical model for carbon storage in forested landscapes /

by Ngo, Nam V.

Abstract (Summary)
An analytical model is developed to address the question of how different disturbance regimes affect the mean and variance of landscape carbon storage in forest ecosystems. Total landscape carbon is divided into five pools based on the processes from which they are derived and based on their temporal dynamics. Formulae for the mean and variance of each pool and the total landscape carbon are obtained for the different disturbance regimes and their dependence of the statistical measures on two key parameters, the observation window and the mean disturbance interval, are analyzed. Comparison of the predictions of the analytical model with those from Maxcarb is included. The analytical solution consistently matches the prediction of Maxcarb. While the analytical model might not replace detailed disturbance simulation models such as Maxcarb, it can more expeditiously provide the qualitative trends of these models. The analytical model might be combined with the results of physiologically-based models (which generally exclude disturbance) to make adjustments for the presence of disturbances in forested landscapes.
