摘要 文中基于大气边界层和植被冠层微气象学基本原理 ,建立了一个森林植被效应的陆面物理过程和二维大气边界层数值模式。并应用该模式进行了植被和土壤含水量等生物和生理过程在陆面过程和局地气候效应方面的数值模拟试验。所得数值模拟试验结果与实际情况相吻合。结果表明 ,应用该模式可获得植被温度、植被冠层内空气温度、地表温度日变化特征 ;森林下垫面大气边界层风速、位温、比湿、湍流交换系数的时空分布和日变化特征。该模式还可应用于不同下垫面 ,模拟陆面物理过程与大气边界层相互作用机制及其局地气候效应的研究 ,这将为气候模式与生物圈的耦合研究奠定一个良好的基础。 Based on atmosphere boundary layer and plant canopy micrometeorology basic principles, a forest underlying surface land surface physical processes model and two dimensional space atmosphere boundary layer numerical model was developed and numerical simulation experiments of biosphere and physiological process of vegetation and soil volumetric water content has been done on land surface processes with local climate effect. The numerical simulation results show good agreement with realistic, which can be used to obtain reasonable simulation for diurnal variations of canopy temperature, air temperature of in canopy, ground surface temperature, and time and spatial distribution of potential temperature and vertical wind velocity and relative humidity and turbulence exchange coefficient over non-homogeneous underlying surfaces. It indicates that the model developed can be used to study the interaction between land surface process and atmospheric boundary layer over various underlying surface and can be extended for local climate study. This work laid a solid foundation for coupling climate models with the biosphere.
