摘　　要：云南地区地震频发,水温观测点分布也最集中,为研究水温异常与地震的关系提供了便利条件.通过收集已经公开发表关于该区域"十五"之前的水温异常与地震的对应关系的文章,较系统地研究了水温异常持续时间、异常空间位置与地震之间的关系.结果表明:水温异常主要是地震短临异常,强震前也存在水温中期趋势异常;一般情况下,地震震级越大,异常范围越广,发震地点通常出现在水温异常集中的区域.In Yunnan,earthquakes happened frequently,as well as groundwater temperature observation points are mostly cen-tralized for its distribution.It is comprehensively collected for seismic cases on water temperature anomaly before the reform, the relationships of seism with water temperature anomaly duration and abnormal space is researched systematically.The result shows that water temperature anomaly is mainly impending-earthquake anomalies,however it has mid-term tendency anomalies before strong earthquakes.Generally,the greater earthquake magnitude,the vaster anomaly range,earthquakes were occurred during anomaly concentration area.The studying achievement has great significance for earthquake prediction and station set-ting.
