一、促进地层学发展的三个因素地层学,在地质科学领域里可称作一门古老的学科.然而,随着近代科学技术和现代化生产的迅速发展,地层学也和其它一些学科一样,在学科内部发生重大变化,形成一些新的方向和分支,出现了新的研究领域.影响和支配地层学朝新的方向发展的因素,有下列三个主要方面.1.相关学科迅速发展,并与地层学深入渗透.地层学是建立在古生物学、沉积学及历史构造学基础上的,它们的发展必定对地层学产生很大的推动.近十多年来,这些学科的分支及新领域,蓬勃发展,地层学从中得到丰富的养分及活力.古生态地层学,就是在这个背景下诞生的.全球性海平面升降变化、古气候(包括古冰期)和古气候带变迁、沉积盆地和沉积相模式,以及板块构造对沉积物的控制等方面的研究新成果和新进展,大大丰富了地层学研究的内容,形成更加坚实的综合研究的基础,并出现了新的地层学方向.
First, the three factors that promote the development of stratigraphy Stratigraphy, in the field of geology can be called an ancient discipline.However, with the rapid development of modern science and technology and modern production, stratigraphy and other disciplines, like, Major changes have taken place in the discipline, forming new directions and branches, and new fields of research have emerged.The following three main aspects influence and govern the development of strata in the new direction: 1. The related disciplines are rapidly developing and Stratigraphy is deeply penetrated.The stratigraphy is based on palaeontology, sedimentology and historical tectonics, and their development will have a great impetus to the stratigraphy.In the past ten years, the branches and new areas of these disciplines , Flourishing, and stratigraphy is rich in nutrients and vitality from which the paleoecology stratigraphy was born.The changes in the global sea level, paleoclimate (including the ancient glacial period) and paleoclimatic changes, the sedimentary basin and Sedimentary facies model and plate tectonics on the sediment control and other aspects of new and new research progress, which greatly enriched the study of stratigraphy, to form a more solid synthesis The basis of the study, and the emergence of new stratigraphy direction.
