%X We have elucidated the importance of investigation on land surface atmosphere interaction for human's living environment protection and local economics development as well as its present state of the art.Based on the previous work,a coupling micrometeorological model for SPAC system over wheat fields in the North China Plain is presented.The leaf stoma non saturation condition is considered to calculate the evapotranspiration,and the root absorption model is revised as well.The canopy is divided into several layers,aiming at revealing the vertical profiles of mean quantities in it and providing scientific basis for parameterization of terrestrial processes.The model is shown capable of well simulating the microenvironment of wheat canopy in good agreement with measured mean temperature,specific humidity and latent heat fluxes, et al .And the sensitivity test is carried out as well to analyze canopy's influence.
