黄河下游土地利用／覆被变化研究对于其资源环境与生态安全具有重要意义．以山东省东阿县为研究区域，以研究区1990、2000年Landsat TM数据和2009年CBERS数据为信息源，利用遥感处理软件ENVI4．7提取了土地利用／覆被数据，结合实地调查，研究了东阿县土地利用／覆被变化的时空特征．结果表明：近20年来，东阿县土地利用类型变化较大．耕地、林地呈明显减少趋势，分别减少45．25km^2、11．65km^2，城乡建筑用地、交通用地呈明显的增加趋势，分别增加44．59km^2、8．06km^2．

In this paper, two TM and one CBERS remote sensing images of Donge in 1990,2000 and 2009 are taken as data for the study. The data sources of land-cover are translated under supervised and un-supervised interpretations with ENVI4. 7. Through investigation of it , the analysis demonstrated spatio-temporal characteristics of Land Use and Cover Change in Donge. The results showed that. the types of land use of Donge changes greatly in the past twenty years. Farmland, forest land reducing, re- spectively reducing 45.25 km^2 and 11.65 km^2 ; urban and rural construction, land for traffic, the trend is significantly increased , respectively increased 44. 59 km^2 and 8. 06 km^2. These changes are mainly be- cause of population increase, the rapid development of social economy culture caused by driving force.
