中文摘要	利用较高分辨率的遥感影像确定出古居延绿洲渠系分布和引水口的位置以及古渠道线路的走向,发现古居延绿洲主要分布在现代绿洲的东侧,至少有6处引水口分布于距雅布赖、东城圈和马圈城一线西侧的水道上.渠系由西向东进入各垦区,各引水口随水道西迁向西延伸.渠系与遗址、古耕地和红柳包间的联系以及~(14)C测年数据表明:多数渠系始建于汉代,以后长期延用,盛于西夏,弃于元末明初;古居延绿洲早期荒漠化始于1300aB.P.;天然水系向西迁移最终导致了古居延绿洲的废弃和完全荒漠化.
英文摘要	The ancient Juyan oasis is located at the lower reaches of Heihe River,Western Inner Mongolia,China. It was a geoponic area under the governing of Han, Xixia and Yuan Dynasties, although it has been desertified in modern time. City mines, abandoned farmlands, remnants of irrigational channels, etc. are scattered broadly in the area, indicating the civilization of ancient agriculture.To better understand the paleo-irrigation channels,water system,and their changes,besides field survey,high-resolution remote sensing images and Corona images are applied. Wheat seeds and tamarix leaves found from the ruined Green City are used for ~(14)C dating analysis while archeological data are also used. The results indicate that the ancient Juyan oasis is located at the east of the modern oasis. At least six irrigating entrances of the ancient water system were found along the line of the western part of Yabulai City, Dong-Chengjuan ( K749 ) City, and Majuan City. The paleo-irrigation channels ran from west to east,following or paralleled to the water channels,to cover through the agriculture area. Most of the paleo-irrigation channels were thought to be built in Han Dynasty, and mainly abandoned in during the boundary of Yuan and Ming Dynasties. The desertification started at 1300aB. P. around Yabulai,Juyan City and other regions,along with the westward movement of the river system.
