| 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. |
