摘要：BadainJaran Desert of Inner Mongolia is arid and rainless all the year around,with much more evaporation than rainfall.But the special groundwater recharge mechanism contributes to the generation of several lakes of different sizes that have never not dried up for years,among which there are many freshwater lakes.As the research object in this paper,East Badain Lake and West Badain Lake in the southeast of the desert,which are less than 50m away from each other,show the considerable difference in mineralization.In fact,one is a freshwater lake,but the other is a brackish-water lake.Considering the underground aquifer structure of BadainJaran Desert and the special formation structure the particularity of the stratigraphic structure around Badain Lake,the author uses AMT(audio magneto telluric)method and ultra-high density resistivity method to analyze the difference in mineralization of East Badain Lake and West Badain Lake from the perspective of geophysical prospecting methods.
