On September 7, 2012, a magnitude 5.6 earthquake happened in Yiliang County, Yunnan Province, it may affect CORS station in Kunming. GAMIT/GLOBK software is used to calculate the data before and after the earthquake of Kunyang and the other five CORS stations. The analysis of the calculating data shows that the YiLiang earthquake affects the geometric deformation of Kunming CORS station, and it makes Kunyang and other six CORS stations have northwest slight deviation.%2012年9月7日，云南彝良县发生5.6级地震，可能会对昆明CORS站产生影响。使用GAMIT/GLOBK软件对地震前后一段时间昆阳等六个CORS站的数据进行解算，然后对解算的数据进行分析得到彝良地震对昆明CORS站的几何形变产生了一定影响，导致昆阳等六个CORS站向西北方向有轻微的偏移。
