依据库姆塔格沙漠东北缘地表水和地下水水文、水化学和同位素相关数据,分析探讨了沙漠东北缘地下水的主要补给来源。结果表明,水体与周边流域地表水并无直接联系,主要受到南部山区贫重同位素水体的补给,但补给过程缓慢,因此,对周边地区水资源的开发非常敏感。根据地势条件和水文地质条件,祁连山沿党河洪积扇到谷地冲湖积平原可能存在一条地下水补给路径,冰雪融水和降水渗透到地下,沿党河洪积扇最终补给到疏勒河谷地。
Based on the data of hydrology, hydration and isotopes of surface water and groundwater in the northeastern margin of the Kumtag Desert, the main sources of groundwater recharge in the northeastern desert rim are analyzed. The results show that the water body is not directly related to the surface water in the surrounding watershed and is mainly recharged by the heavy and weak isotope water in the southern mountains, but the recharge process is slow. Therefore, it is very sensitive to the development of water resources in the surrounding areas. According to the topographic conditions and hydrogeological conditions, there may be a groundwater recharge path along the Party River flood alluvial fan in the Qilian Mountains to the valley plain. Infiltration of ice and snow melts into the ground and the rainfall infiltrates into the ground. Finally, the alluvial fan along the Party River supplies to the Shule River valley .
