摘要

摘要: 对青海湖沉积物进行物质来源进行聚类分析, 并对周边风成黄土与现代湖泊表层沉积物进行粒度分析, 在此基础上, 以青海湖周边典型风成黄土作为风成组分端元, 以青海湖表层沉积物作为水成组分端元, 首次利用已知端元的粒度分布特征对青海湖沉积物中典型粒度分布进行拟合, 进而估算了其中风成和水成组分的比例。结果表明, 青海湖沉积物粒度分布特征可分为三大类:1.水成组分占主导; 2.风成组分占主导(风成黄土主导); 3.两者以不同比例混合。希望此方法能成为未来湖泊沉积物中不同组分的定量判据和古环境的解读提供新途径。

Abstract: This paper reports a cluster analysis on sources of Lake Qinghai sediments, and a grainsize analysis on the surface sediments of Lake Qinghai and its adjacent typical aeolian loess Based on the results, we have fitted the typical grain size distributions of the lake sediments and evaluated the proportions of eolian and fluvial components by using the grain size distributions of given end members, i. e., taking the aeolian loess sediments around the lake as eolian end-member and the surface lake sediments as fluvial end-member. The fitting result shows that the grain size distributions of Lake Qinghai sediments can be grouped into three types:1) dominated by fluvial components; 2) dominated by eolian components (aeolian loess); 3) mixture of both with different proportions. It is hopeful that this method will provide a new way for quantitively partition of different components in lake sediments and for understanding of paleoenvironment. in the future researches.
