| 摘 要： | 在植被和裸地共存的情况下,考虑了植物的某些生态条件,利用热量平衡方程,对于不同气候和生态条件计算了绿洲总的蒸散率以及植被和土壤的温度。研究表明,在某些条件下,蒸散率的解可出现准分岔和多平衡态的形式,它们主要发生在植被覆盖小的地区。

| Abstract: | When vegetation and bare soil coexist, in consideration of some ecological conditions of plant, the total evapotranspiration rate of the oasis and the temperature of vegetation and soil in different climatic and ecological conditions are calculated by using the thermal energy balance equations of vegetation and soil.The evapotranspiration rate depends on climatic and ecological conditions. In some conditions,quasi-bifurcation and multi-equilibrium state appear in the solutions of evapotranspiration rate in the are as covered by small part of vegetation. |

| Keywords: | Energy balance equations Bifurcation Bi-equilibrium state |
