摘　　要：通过提取地倾斜EW分量资料与气温资料作对比分析,认为EW分量短期变化与气温变化关系明显,但年变幅度变化与气温年变幅度关系不明显,且每次阿合奇地震台周围200 km范围内发生中强地震前,EW分量均出现趋势性的倾斜速率改变或者倾斜方向改变,说明该台地倾斜变化趋势与地震对应关系较为明显。而年变幅度与相位所含信息较为复杂,与地震对应关系不明显。In this article, the contrastively analysis on the EW component of tilt observation data and atmospheric temperature shows that there is an obvious relationship between the short-term variation of EW component and atmospheric temperature, but the relationship between the annual variation amplitude of tilt and of atmospheric temperature is not clear. The analysis results also show that the EW component of tilt represented the tendency of rate or direction variation whenever middle-strong earthquakes occurred within the region around Aheqi of 200 kin, suggesting an evident response relationship of the tendency of tilt variation at Aheqi Seismic Station to the earthquakes. Meanwhile, the information contained in annual variation of amplitude and phase is more complicated and is hardly correlated with earthquakes.
