| Abstract: | Kobresia humilis meadow is a typical highland vegetation and main pasture on the Qingzang plateau. The study of modelling of its energy dynamcs is significant to understand interactions between factors, pastural management and ecosystem behavior under stress. The model developed is composed of the following five compartments: above-ground plant portion, below-ground live portion including roots, below-ground dead portion including roots, above-ground litter I (perishable portion), and above-ground litter I (imperishable portion).Energy flows between the five compartments are described by five simultaneous differential equations and parameters in the model were all determined from field experiments.The simulation results exhibited satisfactory agreement with field data.In addition, four-year energy dynamics of Kobresia humilis meadow fenced were simulated. |
