摘　　要：系统分析了地下流体短期前兆异常变化与中强地震的关系,提出祁连山地震带地下流体资料存在两类短期前兆异常,即转折型和单一型短期前兆异常,结合震例对这两类短期前兆异常的特征进行了分析,认为预报人员应特别注意该区内的这两类群体异常的特点,并把它应用到该区的地震预报中。Through systematic analysis on the relationship between the variation of precursory anomalies of underground fluid and moderate strong earthquakes, it is indicated that there are two kinds of short - term precursory anomalies of earthquakes, which are turn style and single style, in Qilianshan Mountain earthquake belt. So it is considered that the approximately synchronous variation for two kinds of anomalies in the region should be given special attention to in the research of earthquake prediction.

关 键 词：祁连山地震带 地下流体 转折型短期前兆异常 单一型短期前兆异常
