【 摘 要 】

In order to solve the problem of shortage of water resources in northern Shaanxi, we selected rectangular large loop source transient electromagnetic method with high water affinity, and radioactive measurement method which can delineate the water storage structure, comprehensive geophysical prospecting methods to look for groundwater. Algorithm has established a forward model, and compared all-time apparent resistivity in late-time apparent resistivity is better than late. We can find out the exact location of the groundwater and thus improving wells rate by comparatively using these two kinds of geophysical prospecting method. Hydrogeology drilling confirmed water inflow of a single well can be up to 40 m3/h, it can fully cover native Domestic and Agricultural water, and provide an important basis for groundwater exploration.
