Abstract
In order to make a more reasonable use of groundwater resources in the Cherchen River Basin in the southern part of the Tarim Basin, this paper uses the multi-year atmospheric precipitation isotope data from two monitoring stations in Hetian and Urumqi to fit the local atmospheric precipitation line LMW: δD=7.5 δ18O+5.9(n=178,R2=0.9526). Combined with the local hydro-geological conditions, this paper explores the groundwater supply source of Cherchen River Basin in Tianma County by using the variation characteristics of surface water and groundwater isotopes (δD, δ18O, T) of different geomorphic units and the relative change rule of Cl- δ18O. The results show that the groundwater of different geomorphic units in the study area is mainly supplied by glacial snowmelt water and alpine rainfall, and the source area is the southern high mountain area. In addition, in recent years, water-saving facilities such as canals and civil wells are built to divert water for irrigation, so that the groundwater in the irrigation area is also supplied by a large number of canal system diversion water and seepage of backwater from farmland irrigation. In the desert area, the T isotopes of groundwater are low, and the δD and δ18O values are close to the local atmospheric precipitation line, so it is speculated that the groundwater in this section is also recharged by local atmospheric precipitation.
