相似优先比法研究巴丹吉林沙漠及周边地区地下水补给

位于中国内蒙古西部的巴丹吉林沙漠东部存在高大固定沙丘与湖泊共存的景观,湖泊中存在上升泉,且沙丘内部潮湿．沙漠以北的拐子湖和古日乃草原也有上升泉的出现．本文采用聚类分析中的相似优先比法结合水化学因素对巴丹吉林沙漠及其周边地区不同地点的水样进行分析,由此得出祁连山上的冰川融水与沙漠湖泊及以北地区的地下水相关性良好．

Application of similarity priority ratio on resources of groundwater in Badain Jaran Desert and its surrounding areas

Badain Jaran desert lies in the northwest of Mongolia. In the eastern desert, the coexistense of lots of lakes surrounding big immovable sand dunes, the peculiar influences of wateriness inside the sand dunes and ascending springs in the lakes have been found. Similar conditions occur in its north and northwest areas. In this paper , combined with hydro chemistry factors, a method similarity priority ratio is firstly applied to analyze some water samples of different positions in Badert Jaran desert and its surrounding areas. And a result that it has a good hydraulic relation on the snow water of Qilian Mountain and lakes in the desert and ground water in some surrounding areas has been given.
