摘要: 根据未来气候变化的趋势,利用生态信息系统(EIS)技术,采用修正后的Holdridge生命地带模型,并结合海拔因素,模拟了四川盆地在未来气候5种水热条件下可能出现的生命地带类型。结果表明,随着未来全球气温的升高,四川盆地内森林地带总分布面积将增加,高山草甸或冻原地带分布面积将减少,亚热带荒漠地带将出现,整个生命地带的分布将会沿东南至西北方向发生类型和地界的推移.

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.

Key words: Duck, RAPD, Genetic diversity, Genetic distance, Ecological type
