In this articl, the background, the thoretical source and the basic content of Cuvis catastrophism are discussed, It is shown that it is not a subjective fabrication by Cuvier, but rather it is inherited from reforming former catastrophic ideas, on the basis of his long-term scientific practic, Therefore it helped to push forward the dvelopment of gology and biology.
本文论述了居维叶灾变论的产生背景,理论来源及其基本内容,证明它并不是居维叶的主观臆造,而是他在长期科学实践基础上对前人灾变思想的继承和改造。因此它对地质学和生物学的发展曾起到巨大推动作用。本文还论述了居维叶灾变论与其它灾变学说的区别;并列举大量现代科学发现证明居维叶所谓的灾变是不可否认的事实,是自然界中具有确定原因的必然发生的历史事件。
