One dimensional Numerical Simulation of the Land Surface Ecological Processes

A transfer model is established,which can be used to study the interaction between atmosphere,vegetation and soil. The model is composed of multilayer atmosphere,multilayer soil model and vegetation model which are coupled by balance equation describing the energy and moisture transfer at the interface. A series of tests are preformed to assess the sensitivity of the scheme to the inclusion of variable soil and vegetation characteristics. The results show different vegetation cover,different soil and vegetation types and precipitation exert great influence on energy,water transfer between soil,vegetation and atmosphere. The model developed can be coupled in mesoscale models to study the interaction between land surface processes and the atmosphere in inhomogeneous regions.
