Abstract:

Based on the distribution of active falt and recent earthquake centre,the bordering land ofNingxia and Nei Mongol can be divided into 8 tectonic earthquake belts,and the characteristicsof the earthquake energy which has be released since 1970 as well as of the temperal-spatial distrbution is studied for 8 tectonic earthquake belts.The energy release indicates that the borderingland of Ningxia and Nei Mongol will be in an active peridof earthquake within several years.Authors have forecasted the causative sites for potential mederate－strong earthquake occurring inthis region in view of the earthquake prediction.

Key words: Ningxia, Nei Mongol, Tectonic eartkquake belt, Seismicitics, Earthquake prediction and forecasting

摘要：

根据活动断裂和近代地震震中分布,对宁夏内蒙古交界地区做了构造地震带的划分。研究了该区8个构造地震带1970年以来地震能量释放特征及地震时空分布特征。在指出该地区未来数年将处于地震活跃时段的基础上,对中强以上地震可能发生地点做了探讨,此项研究结果对地震预报有一定意义。
