摘　　要：本文根据磁异常、重力异常和天然地震P_n波走时统计所反映的上地幔波速各向异性特征,运用伸展构造的理论,从深部构造的角度,探讨了依—舒地堑的成因问题。This paper studies the genesis of the Yi- shu graben structure in line with the mechanism of structures in the depth of the earth as well as the extension theory of structures ,in which the data of magnetic/gravity anomalies and the statistics of the natural seismic wave Pn's travel times in response to the anisotropic features in the upper mantle are exploited.

关 键 词：依-舒地堑 深部构造 上地幔
