[Objective] In order to provide technical reference for the study of the relationship between plant and groundwater depth in desert areas and the search for groundwater resources, several rapid and accurate techniques and methods for obtaining groundwater depth in desert area were analyzed and selected.[Methods] Through the analysis of observation wells, soil impedance coefficient, ground penetrating radar and nuclear magnetic resonance, the principles, advantages and disadvantages and application of several methods for measuring groundwater depth, such as seismic exploration technology, and factors such as comprehensive operation convenience, accuracy and equipment price, etc., are analyzed to select several rapid and accurate techniques for obtaining groundwater depth in desert areas.[Results] When detecting groundwater depth in desert area, we should be familiar with the principle, advantages and disadvantages of these methods, and consider the convenience of technical operation, data precision and the price of instrument and equipment, labor costs and other factors as well to comparative trade-off analysis for the selection of scientific, reasonable technical programs.[Conclusion] It is the cheapest and most accurate method to determine the groundwater depth in desert area, and when the terrain conditions are complex and the traffic is not convenient. Nuclear magnetic resonance (NMR), seismic detection in one case, if groundwater depth is measured in homogeneous sandy land, a soil impedance meter could be used.
