结合朝阳及周边地区地震，分析地震前朝阳地倾斜观测数据异常变化，结果表明朝阳地倾斜观测在周边Ms≥3．0级地震发生前存在较明显的震前倾向异常变化，并具有以下特征：（1）同一方位的地震，震前出现地倾斜倾向异常的分量具有统一性，且加速方向具有一致性；（2）朝阳地倾斜观测倾向异常有较强的方向性，但幅度特征不明显，与震中距关系不大。

Combined with the earthquakes in Chaoyang and surrounding area, the abnormal changes of observation data of ground tilt are analyzed. The results showed that there were obvious changes before Ms≥3.0 earthquakes occured And it has two characteristics as the following showed: (1) Earthquakes of the same range, has the unified components of the ground tilt abnormality before the earthquake occured; ( 2) Chaoyang ground tilt observation tendency anomaly has a strong direction, but the amplitude characteristic is not obvious, which has has little relationship.with the epicentral distance.
