This paper expounds the principle, mode, applicable conditions, advantages and disadvantages of the discharge method for detecting groundwater resources, and introduces the occurrence, distribution and supply flow direction of groundwater in Pengyang County from the macro level. This paper discusses the specific application and practice of the discharge method in the detection of groundwater resources in Pengyang County. The practice shows that the discharge method is simple, low-cost, fast and effective, and has certain feasibility, accuracy and scientificity in the macroscopic budget estimation and long-term prediction of groundwater resources detection, which is worthy of popularization and application in similar areas and similar areas.<br>
