A model of terrestrial carbon cycling as it is affected by land-use activities such as forest harvest and clearing is described. A compartment model simulates carbon cycling responses of ecosystems to harvest and clearing perturbations. An area distribution function summarizes the extent of ecosystems according to carbon density in vegetation per unit area. Through time, plant growth and land use alter this area distribution function with opposing tendencies. Simulations agree reasonably well with previous studies. Discrepancies appear to be associated with dead organic matter responses.
