【摘要】 以巴丹吉林沙漠及邻区为例,基于距离空间基本原理,对水样化学成分进行了离散性、主成分和相关性分析,指导样品数据采集和化验。计算结果表明,祁连山冰川融水自身化学成分在该地区聚类最高,多次聚合说明祁连山冰川融水是该地区地下水补给源。由聚类图推测:祁连山冰川融水通过地下首先经过诺尔图,然后到达古日乃和拐子湖;古日乃和拐子湖地下水某些样品聚合距离大,可能是由黑河水渗入引起的,少量黑河水可通过古日乃渗入拐子湖引起地下水成分变化;没有迹象显示黑河水补给巴丹吉林沙漠(以诺尔图为代表)地下水。更多还原

【Abstract】 Taking the Badain Jaran Desert and its neighboring district as an example, discreteness, principal component and correlation of the chemical constituents of water samples were analyzed for the benefit of data collection and test. It is concluded that the chemical constituents cluster of glacier melt water in the Qilian Mountain is the highest one in the region, and the glacier melt water is the main groundwater replenishment source. Clustering figure shows that, along the route groundwater seepage, the melt water first recharges groundwater of Nuoertu, then that of Gurinai and Guaizi Lake; the long clustering distances of groundwater samples of Gurinai and Guaizi Lake perhaps result from infiltration of the Heihe River; it’s impossible that water of Heihe River recharges underwater of the Badain Jaran Desert represented by Nuoertu.更多还原
