The contact relationship between the Ejina Basin and the Badain Jaran Desert can be used to analyze the Ejina Basin groundwater level drops and the environmental degradation. By comparing local geological and geophysical methods of data analysis, the reasonable and effective audio magnetotelluric (AMT) geophysical methods are selected in the region to carry out original and innovative explorations, and a good result is achieved. Survey results suggest that the Ejina Basin is in rising, Badan Jaran Desert in declining, the lithology thinknesses on both sides see a great change, and the contact between the Ejina Basin and the Badna Jaran Desert is an extensional fault. The results can provide a basis for the analysis of the groundwater transforming relationship and, the Ejina Basin groundwater level declining in the studied area, and for the study of the groundwater formation mechanism in basin and desert, which is of important social significance for the recovery and the management of the ecological environment in the Ejina Basin.
