选择生态环境脆弱的艾比湖流域内绿洲为研究对象，以1990年、2001年、2010年三期TM和ETM＋影像为数据源，采用SVM分类方法进行土地利用／覆盖类型分类、统计与分析研究区20年土地利用／覆盖时空动态变化。研究结果表明：1）1990～2001年除了裸地面积减少外，其他地类均有增加，且耕地面积增加幅度最大，面积增加了483．42km^2。2001～2010年除了耕地面积增加了488．87km^2，其余地类的面积都有不同程度的减少。而研究期间裸地面积一直呈现不断下降的趋势，在20年间共减少了1186．43km^2。2）经济发展、政策、人口以及自然环境等驱动因素对研究区土地利用结构变化影响甚为显著，而人口迅速增加对农产品的大量需求促使耕地变化剧烈，面积大幅增长。因此，合理地控制人口数量，正确的政府政策导向和合理经济发展需求是干旱区绿洲土地可持续发展的关键。

This paper chooses the Ebinur lake region oasis as a study area, using support vector machine (SVM) to classify land use /land cover types based on the three periods (1990,2001,2007) TM and ETM + satellite data, and analyze the dynamic change of land use / land cover in recent 20 years . The results show that: (1) from 1990 -2001, except decrease of the bare land area, the rest of class increased with the fastest growing area of cultivated land which has been increasing 483.42 km. And from 2001 to 2010, in addition to the increase of 488.87 km areas of cultivated land, the remaining areas of land type were on the decline. From 1990 to 2010, the bare land area has decreased 1186.43 km. (2) Economic development, national policies, population growth and climate factors are driving forces of land use type change. Also rapid population increase in large demand for agricultural products prompts the violent change of cultivated land area of substantial growth. Therefore reasonable population control, government policy - oriented and rational economic development needs are very important for sustainable development of arid oasis land.
