摘　　要：地层学和古生物学作为地质学的重要基础学科,近年来无论是在研究的内容上或是研究的方法和手段上都发生了重大的变化,随着现代科学技术的发展以及我国国民经济建设的需要,它们的研究方向和目的也必将发生深远的变化。因此,地层学和古生物学工作者在观念和思想方法上也应当有一个相应的转变,现代地层学和古生物学研究不再是仅仅着眼于地层层序的建立及其时代的划分、对比以及生物群的特征描述和其时代的确定,而是更多地着眼于它们的时空分布特征、演化规律和成因环境、生态环境的追索及其所反映的古地理背景、古构造格局演变等方面的综合研究,它们的研究方向和目的也已经由为一般地质研究服务转变为直接参与重大的地质研究,地学不同学科的相互结合与相互渗透已经成为地层学和古生物学研究中不可逆转的必然趋势,而且地层学和古生物学本身也已经成为一个集成度较高的综合研究实体,正在朝着系统地质学的方向发展,只有积极地参与并引导这种发展趋势,古生物学和地层学的研究才能够健康地发展。Following the development of modern sciences and technology, paleontology and stratigraphy have been greatly expanded in their research scope and contents. Paleontology and stratigraphy no longer restrict themselves only to biotic description and stratigraph-ic subdivision and correlation as well as the setting up of stratigraphic sequences, but they involve a much broader scope of studies coordinating with many other disciplines. They have, therefore, become an integrated and important aspect in the geological studies. Though paleontology and stratigraphy mainly deal with the organic and inorganic records in the geological past and try to present a reasonable explanation to the geological development of any concerned region in the past based on these records. without the support of other branches of geology, however, it is impossible to accomplish such an important task. The world is naturally a well-organized system in which one thing is closely re- lated to another by some links. In geological studies, this is especially true when dealing with the evolution of the biotas. The biosphere, lithosphere and hydrosphere have formed a mutually interrelated system. Changes in one aspect would surely cause corresponding changes in all other aspects. Therefore, the studies of paleontology and stratigraphy can not concern themselves only within their old confines. They should search for a wide cooperation with other disciplines in the earth science and build themselves on a more solid and broader basis.
