中国河流沉积学研究20年

Advances in Chinese Fluvial Sedimentology from 1983 to 2003

从河型及其分类研究、现代河流沉积调查、河流沉积相与相模式研究、河流相地层的层序地层学研究、河流沉积砂体建筑结构精细解剖、河流沉积模拟研究等六个方面回顾了自《沉积学报》创刊以来 2 0年中国河流沉积学研究的主要进展 ,指出我国的河流沉积学取得了许多富有特色的研究成果 ,主要表现在网状河概念的引入与普及、建筑结构要素分析法的推广、界面层次的划分和及其概念的扩张、岩石相类型和岩石相组合概念的应用、河流砂体露头调查的方法与技术、沉积构造的沉积动力学解释、层序地层学在河流沉积研究中的应用、河流沉积过程的模拟实验、河流相储层的建模技术等方面。但是 2 0年来 ,中国河流沉积学研究并没有出现国际公认的理论首创 ,应当加强河流沉积学的研究组织 ,吸收地理地貌和水利学的研究成果 ,结合社会经济建设需要不断扩大河流沉积学的研究领域 ,积极进行国际学术交流 ,使我国的河流沉积学研究走在国际河流沉积学研究的前列。

Progress in Chinese fluvial sedimentology, beginning with the initial issue of ACTA SEDIMENTOLOGICA SINICA in 1983, have been reviewed respectively from the aspects of classification of stream, modern present deposits investigation, fluvial facies and depositional models, fluvial deposits sequence stratigraphy, fluvial architecture element analysis and fluvial sedimentological simulation. The great achievements, which have been made in this duration by Chinese fluvial sedimentologists, including the application of the new concepts of anastomosing stream, architecture element analysis, lithofacies and facies assemblages, sedimentary structure research, outcrop investigation, physical and digital simulation of fluvial sedimentology and fluvial sequence stratigraphy, have been concluded in this paper. However, there are no our own new theory which has been known worldwide.To make Chinese fluvial sedimentology front rank in the world fluvial sedimentology, the organization of such research should be reinforced, achievements in geography and hydrology should be absorbed, the domain of the research should be expanded with the demanding of the gradual development of the social economy , international exchange activities should be encouraged positively.
