摘　　要：2008年8月30日,攀枝花市与西昌市会理县交界处发生了6.1级地震,在这次地震前,攀枝花川-05井的数字气氡出现了明显的异常变化。综合分析认为,气氡观测存在短期、临震异常的同时,还存在中期趋势异常。本文主要对8月30日地震前,气氡观测资料的异常、机理及有关问题进行了分析和讨论。AnM6. 1 earthquake struck the boundary between Panzhihuan City and Huili County on 30 August 2008. Before this earthquake, the content of the escaped gas radon from ground water shows a clear change. After this earthquake we think that the content of the escaped gas radon from ground water show a middle-term abnormal, short-term and impending abnormal change. We call these abnormal changes the near earthquake hypocenter and discuss these problems.
