摘要: 应用植被对地表面与大气之间水热交换影响的参数化模型,研究了不同植被类型的覆盖度、土壤湿度下垫面的土壤温度、叶温、近地面层气温及地表面与大气之间热量和水分交换。并与相应的观测资料进行了比较。结果表明,模拟不同植被的温湿状况、辐射特征和能量平衡关系是合理的。因此,该参数化模型可应用于中尺度气象模拟、气候模拟和环境生态学的研究。

Abstract: This paper advances a parameterized model to study the influence of vegetation on themoisture-heat exchange at near-ground layer.With this model, the moisture-heat exchange between earth surface and atmosphere is studied under conditions of different vegetation and soil moisture regime.The results show that the simulation states of temperature, moisture, radiation and energy balance are reasonable, and thus, this parameterizedmodel is capable of using to study mesoscale meteorological modeling, climate modelingand environmental ecology.
