【摘要】 发展了一个简单的地气相互作用模式 ,讨论了不同气候和植被条件对绿洲消长的影响。结果表明 ,能使绿洲扩大的主要条件是低纬度、小尺度 ,并具有低水汽、较高温度的环境以及较小气孔阻力的植被。这一简单的理论分析对发展复杂的数值模式和对观测的布局有参考意义 ,对治理荒漠也有一定的启示。更多还原

【Abstract】 In this paper, we construct a coupled system of oasis and atmosphere based on an oasis evolvement model by adding atmospheric motion to discuss how different climate and vegetation type have the effect on oasis. The results indicate: lower latitude, smaller horizontal scale, lower humidity and some vegetation with small stoma resistance are good to develop oasis. The simple conclusions are helpful to develop complex number model and deal with desert.更多还原
