| 摘 要： | 用一个三维模式实施了５个数值试验，研究了植被覆盖与裸土之间的非均一性对局地气候的影响。结果指出：存在着一个最适宜的植被区面积Ｓ＿ｃ，当Ｓ＝Ｓ＿ｃ，这种非均一性激发的上升运动最强，上升气流区的空间范围最大。

| Abstract: | Five numerical experiments were performed by using a three dimensionaI numer-ical model in order to study the impact of inhomogeneity between vegetation cover and baresoil on local climate.The results show that there is the most suitable vegetation area(S_c)As-suming that S=S_c,ascending motion is the strongest by the stimulant of inhomogeneity.Space range of updraft zone is the bigest. |
