摘　　要：通过整理和解剖青藏高原东北缘地震重力观测资料,分析研究了青藏高原东北缘重力场时空变化及其与地震活动的关系,研究了强震孕育发生过程重力异常特征及震后异常效应。Through collection and analysis of repeated measurement of gravity data in the northeastern edge of Qinghai-Tibet plateau area, the relationship between temporal-spatial changes of gravity and earthquake activities has been studied systematically. Characteristics of gravity abnormality appeared during the seismogenic process of stronger earthquakes preparation, and gravity anomaly effect after the earthquakes are also studied.
