Abstract Loess plateau with very complex geological conditions is considered to be a world-class thorny problem.Liupanshan basin in southern Ningxia belongs to the typical loess tableland geomorphology and sedimentary basin,and its exploration is of low degree but has great potential.Geological conditions of the area is very complex with a great thickness of loess layer covering the surface,and deep conditions in different tectonic units are very different,so we must overcome the double impact of surface and underground in the seismic acquisition.In this paper,in combination with the data available and the application of new technologies and new methods,the authors analyzed the areas with different geological conditions and the difficulties in exploration and, on such a basis, summed up a series of seismic acquisition technologies with the purpose of guiding the exploration work in this area.
