MODELS AND NUMERICAL SIMULATIONS OF ATMOSPHERE-VEGETATION-SOIL INTERACTIONS AND ECOSYSTEM DYNAMICS
Various climate-environments Mid the diversity of ecosystems are determined by the external energy exchanges and the internal interactions between atmosphere, ocean, land, biosphere and so on. Essential features of these interactions are shown through the application of some simplified atmosphere-vegetation-soil interactive models with other prescribed atmospheric variables. The qualitative analysis and quantitatively numerical modelling demonstrates multiple time scales and pronounce nonlinearities. These show that the wetness in the rooting zone of the soil can influencing the variability of atmospheric climate for one month up to two seasons via the variation of evapotranspiration, and that the ecosystems (environment-vegetations) can be self-organized and undergo bifurcation as some parameters vary with time and space. The models have been validated by some field observations. The model parameters can be adjusted by field observations and satellite remote sensing data.
