The Effects of Climate on Development of Ecosystem in Oasis

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.
