摘要/Abstract

摘要： 基于大气边界层和植被冠层微气象学基本原理,建立了一个森林生态系统与大气边界层相互作用的数值模式.应用该模式模拟了森林生态系统的热量平衡、植被温度、植被冠层内空气温度、地表温度日变化特征,及森林生态系统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廓线的日变化特征.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区域气候效应的研究,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.

Abstract: 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.

Key words: Forest ecosystem, Atmosphere boundary layer, Numerical simulation
