| 摘 要： | 本文用一个二维数值模式,实施了六组试验,分析了植被带不同布局对局地温度场和垂直速度场的影响。结果指出,若植被带布局得当,植被—裸地之间的非均一性可望激发出更强的上升运动。这对于半干旱区对流性降水的形成是有利的。

| Abstract: | A two-dimensional model is used to analyze the effects of various arrangement of fores zones on the distributions of local potential temperatures and local vertical velocities. Results of six numerical experiments manifest that more intense vertical cell excited by the plant-bare soil horizontal inhomogen-ties can be expected in case the arrangements of forest zones are morer ational which is favorable to the formation of local convective rain in the quasi-arid regions. |
