湖盆碎屑沉积物在长期积累过程中,它的理化性质、物质组成和沉积厚度,不仅对湖盆演变和生态环境起影响作用,还可为工农业生产提供大量沉积矿藏。因此,开展现代湖盆沉积物类型和特征的研究,在理论、实践中将起积极作用。本文通过对长江中下游、云贵高原、松辽平原、新疆、青海及西藏等地近30个不同成因的湖盆的调查,试图就我国湖盆碎屑沉积物的类型划分原则及其特征作系统分析,为开展湖盆沉积物的研究提供依据。
In the long-term accumulation process, its physical and chemical properties, material composition and sedimentary thickness of lake-basin detritus sediments not only have an effect on the evolution of the lake basin and the ecological environment, but also provide a large amount of sedimentary deposits for industrial and agricultural production. Therefore, the research on the types and characteristics of sediments in modern lake basin will play an active role in theory and practice. Based on the investigation of nearly 30 lakes with different genetic origins in the middle and lower reaches of the Yangtze River, the Yunnan-Guizhou Plateau, the Songliao Plain, Xinjiang, Qinghai and Tibet, this paper tries to make a systematic study on the principles and characteristics of the types of clastic sediments in the lake basin in China Analysis, to provide the basis for the study of lake sediments.
