摘要
对全球大震时空特征的分析表明，北南半球大震分布与陆地面积成比例，全球强震活动具有35年的地极移周期，并对一些具有全球活动特征的构造事件进行了机理探讨，最后对大陆西部强震的活动规律．尤其是主体活动区的特点进点了仔细的研究。给出了未来一段时间内的预测结果。
By analysing the time-space distribution of strong earthquakes in the globe, the resultsshow that earthquake distribution in the south and north hemispere is proportional with landcoverage. and the global strong seismicity is 35 years period of the Earth polar shift. Theauthors discuss the global tectonic mechanism, and study the active law of strong earthquakesin western China. they especially study the characteristics of main active areas, and get theprediction results.
