| 摘 要： | 为定量描述土壤-植被-大气连续体的热量及水分交换，建立了以有效比湿等为基础且具普适性的植被参数化方案——1种等温大叶模式。利用拉萨、狮泉河和南京3个试验站的气象观测资料验证并由此计算的感热通量和潜热通量以及净辐射量、土壤温度等观测结果进行对比分析表明，该植被参数化方案成功地反映了下垫面的水、热传输特征。

| Abstract: | In order to describe in detail thermal and hydrological exchange in soil-vegeta tion-atmosphere continuum,a simple and universal scheme of vegetation parameter ization is established based on the effective specific humidity.It is an isother mal "big leaf" scheme.The scheme is tested using observation data from three exp erimental stations and the computed sensible heat flux,latent heat flux,net radi ation and soil temperature have been compared with the observations,the result s hows that this scheme could describe the transfer feature of heat and water succ essfully |
