| 摘 要： | 发展了一个裸露土壤的参数化数值计算方法，检验了土壤物理参数对土壤－大气界面热通量和水汽通量计算的敏感性。结果表明，土壤工是最重要的土壤特征参数，它直接控制着地表和大气之间水，热通量的输送强度和热量平衡。

| Abstract: | A numerical model is developed for simulating microclimate of bare soil,which is incorporated in one dimensional boundary layer model.The sensitivity of the scheme to several soil physical parameters is evaluated.Numerical simulated results indicate that the most important soil characteristic parameter is the soil moisture,and next is the surface albedo,which regulates the heat balance and the strength of the fluxes of heat and moisture between the atmosphere and the ground. |
