摘要

Tibetan Plateau is a special block of Eastern Asia. The compound geophysical fields indicates that Tibetan Plateau is divided into eastern and western subareas by complicated force system that compress in NS direction and expand in EW direction. Their boundary is around the rang of 90°±2°E. It means that Tibet is composed of three parts (west, middle and east). In the middle zone, the gravity field, geomagnetism field, geothermal field, seismology field, properties of deep medium and structure and its composition are quite different from the eastern and western parts, which indicate that the deep process and dynamical response are different in the whole plateau.
