DYNAMICS AND NUMERICAL SIMULATIONS OF HYDROLOGICAL VEGETATION-SOIL INTERACTIONS

摘要：

Taking known atmospheric variables, we developed a simply vegetation-soil inter-active model in hydrology. The model consists of three layers, canopy of vegetation c, surface layer of soil s and root zone of soil r. Their water contents are interac-tive due to the processes such as evapotranspiration and runoff occurring in each layer and the conductive transfer between s-layer and r-layer. The processes are written in parameterization formulas. The only external input of the model is the atmospheric precipitation. Analysis of numerical simulations indicate that the model can capture essential features, such as multiple time scale of the three layers and the nonlinear frequency shifting. The later implies the important role of root zone in influencing the atmospheric precipitation, hence influencing the short-term climate variability.
