     Due to the thick losses layer, developed gullies and relief of sharp variety, it is difficult to conduct surficial and shallow geological seismic survey in Longdong region. The paper introduced the geological conditions for seismic survey, and determined the parameters for work based on experiments. The results show that the design of 10-line 25-artillery observation system is good performance on high stacking fold, wide azimuth receiving, offset is larger, the parameters of observation system are able to meet the requirements of field data acquisition by means of 3D seismic exploration.
