主　　题：Southeastern margin of the Qinghai Tibetan Plateau Seismic strain energySeismic cycle Seismic risk 

摘      要：Using the methods of the Gutenberg magnitude energy empirical formula and the Benioff seismic strain energy release curve,we make a systematic study on seismic strain energy release of historical earthquakes in the southeastern margin of the Qinghai-Tibetan Plateau since *** paper provides a periodic table of the earthquake strain energy release in the fault zones and the fault block *** study shows that seismic strain energy release is strong in the east and south,and weak in the west and *** overall seismic strain energy release of the Yushu-Xianshuihe-Xiaojiang fault system is consistent with the quasi-periodic *** seismic cycle of some fault zones and fault block areas shows synchronization to a certain *** risk cannot be ignored in the current large release period of seismic strain energy in the southeastern margin of the Qinghai-Tibetan *** seismic risk analysis shows that seismic risk is very high on the Anninghe-Zemuhe and Xiaojiang fault *** dangerous zones need follow-up *** future,it is necessary to combine different research methods to improve the reliability of seismic risk assessment.
