Abstract: According to the trend of climate change in the future and combing the elevation factor, the authors simulated the life zone type of the probably emergence of Sichuan basin under 5 kinds of hot and water conditions by using ecology information system (EIS) technology and Holdridge's life zone model which was revised . The result indicated that along with the whole world going up of air temperature in the future, the total distribution area of forest zone will increase and the distribution area of Alpine meadow/Tundra zone will decrease, and the Subtropical Desert zone will appear in Sichuan basin, the whole life zone will be occur elapsing of the type and the boundary of land followed the southeast to northwest.
