The acquisition operation on complex mountains is a systems engineering having a high cost and high risk, scientifically and reasonably designing seismic line layout and acquisition parameters on mountains is a basis of lowering both cost and risk.Starting from heavy energy losses of effective signal that is a key factor of influence on the quality of seismic data on complex mountains,the paper systematically analyzed the factors causing energy losses of effective signal,absorption on surface and in strata and mechanism of diffraction and shield.The design principles of seismic line layout and acquisition parameters on complex mountains are put forward on that basis and are applied in Quele area of Tarim basin, which achieved good results.
