摘　　要：永胜地震台形变观测资料存在年变现象,为分析年变影响因素,基于该台形变观测数据,与台站东北方向的羊坪水库蓄放水数据进行相关性分析,结果表明,永胜地震台形变观测资料(除分量应变外)的年变形态,主要由羊坪水库的蓄、放水引起。Yongsheng Seismic Station deformation observations show annual variations. In order to analyze the annual variation causing factors, this paper uses deformation observation data and the Yangping Reservoir water storage data to carry out a correlation analysis. The results show that the annual variation feature of the deformation observation data(except for the component strain) is mainly caused by the storage and discharge of the Yangping Reservoir.
