| 摘 要： | 构造事件是否存在节律性，长期以来一直存在着不同的意见。根据国内外最新研究结果，笔者认为构造事件、生物灾变事件、巨大陨击事件、气候与环境变化都能表现出一定程度的节律性、周期性或旋回性。在一些大陆边缘地区，构造作用表现出几千万年相对的稳定期和数百万年的活跃期（突变期）相间的演化过程，而在板块内部与造山带，节律性则可能表现得不太明显。岩石圈上各地区的构造活跃期，由于应力集中现象缓慢传递的结果，而表现出全球不同时的特征。看来，构造事件尽管都是流变作用的产物，但仍然具有节律性，不过各地区存在着不等时和不同时的节律性。

| Abstract: | The problem on the rhythm of tectonic events is still controversial in long term. According to the recent research results at home and on abroad, the author has considered that the tectonic event, biotic extinction, giant extraterrestrial impact, change of weather and environment are able to show the rhythm periodicity or the cycle to a certain degree. In some continental margin areas, the tectonic process manifests the interval evolution between the relatively stable stage with several ten million years and the active stage (sudden change) with a few million years, while in the inner plate or orogenic belt, the rhythm may be showed not very clear. The tectonic active stages in different areas of lithosphere happened at the different time on the globe, owing to the result of slowly transferring of stress concentration. Thus, although the tectonic events are the results of rheology, they still have the rhythms with unisochroneity and uncontanporaneity in various areas. |
