摘要: 额济纳地区2ka来水系有自东向西迁移的过程, 主要受水尾闾湖从东部古居延泽向西部东、西居延海转移; 绿洲时空分布格局也随水系从古居延绿洲向额济纳绿洲发生迁移; 荒漠化过程则由古居延三角洲下部向中部和中上部扩展。

Abstract: The water system of lower Heihe River in Ejin region has experienced the migrating processes from east to west in the past 2000 years. Simultaneously, the main terminal lake that accepted inflowing water migrated from the Gujuyanze Lake to the East Juyan Lake and West Juyan Lake. As result, the oasis distribution migrated from the Gujuyan old oasis to the Ejin new oasis along with the water system shift. Without water supply the desertification process on Gujuyan old oasis spread from the lower part to the central and upper parts of the Gujuyan alluvial dealt.

Key words: Heihe river basin, water and land resources, Ejin region, environmental evolution
