With the economy development and population increase of Dunhuang, the pattern of water exploitation changes with each passing day. A tremendous demand for underground water results in excessive pumping, and water level falls sharply. Environments which focused on water resources become more and more maladjusted, and Crescent Spring which called as desert resort will dry up nearly. Finding out hydrogeological condition of Crescent Spring in Dunhuang and underground water circulation rules, and underground water recharging of Crescent Spring sufficiently and timely is an anxious problem to be resolved, which is important in economic merit and society significance. Based on the difference in physical property between fault, water conducted ancient riverways and their ambient rocks, an audio frequency magnetotelluric method was applied with geological data to determine distribution of water conducted structures, which provides reliable data for geological environment governance of Crescent Spring. The results obviously show that there are faults and water conducted ancient riverways in Crescent Spring and its ambient area. The conclusion can be drawn that evident geological effect can be obtained by audio frequency magnetotelluric method to define location of fault and water conducted ancient riverways and it can provide scientific foundation for underground water recharging in Crescent Spring.
