[Numerical simulation of interaction between forest ecosystem and atmosphere boundary layer].

Based on the basic principles of atmosphere boundary layer and plant canopy micrometeorology, a numerical model of the interaction between forest ecosystem and atmosphere boundary layer was built, and used to simulate the diurnal variations of heat balance in forest ecosystem, canopy temperature, air temperature in canopy, and ground surface temperature, as well as those of the profiles and temporal and spatial distributions of potential temperature, wind speed, specific humidity and turbulence exchange coefficient. It indicated that the model could be used to study the interaction between land surface process and atmospheric boundary layer over various underlying surface and regional climate effect, which supplied a solid base to the researches on coupling climate models with the biosphere.
