| 摘 要： | 在地形坐标系中建立一个三维静力平衡的大气-土壤耦合模式,模式主要考虑了复杂地形和植被的热力及动力过程。与其它中、小尺度模式相比,此模式在地表与植被冠层建立的辐射平衡方程和能量平衡方程中,均详细考虑了坡向、坡度的影响。通过对贵州石漠化危险区最典型的贞丰县气候效应数值模拟表明:所采用的大气-土壤耦合模式,能较好模拟贵州石漠化区域气象要素的空间分布趋势;中等程度石漠化区域向高强度石漠化区域演变过程中,气温场表现为先轻微上升,上升到一定程度后剧烈下降,然后当其演变到强度石漠化程度后,继续向超强程度石漠化演变,其气温表现为剧烈的下降趋势。

| Abstract: | In the terrain,a three-dimensional coordinate system of static equilibrium atmosphere-ground-coupled model was created.The thermodynamic and dynamic process of complex terrain and vegetation was taken into consideration in this model.Compared with other medium and small-scale model,the aspect and slope effects are all considered in detail in the establishment of the radiation balance equation and energy balance equations between the surface and the vegetation canopy.The results showed that the atmosphere-gr... |
