| 中文摘要: |
| 本文详细梳理了210Pb和137Cs计年法在尼罗河三角洲泻湖沉积年代学研究的历史过程以及遇到的困境,并结合笔者近期研究结果,进一步论证了该手段在近百年湖泊沉积速率测定和沉积过程研究等方面仍具有较高适用性。同时,笔者从钻孔采样位置、岩性状况、采样间距、计算模式等四个方面提出了在实际应用210Pb和137Cs计年中应注意的细节,以期为今后该手段应用于湖泊环境污染年代测定研究取得理想效果提供一定理论帮助。 |
| 英文摘要: |
| This paper elaborated the application history of 210Pb and 137Cs in the lagoons of the Nile Delta and the difficulties involved in previous studies. The recent study by the author has further confirmed the utilization potential of 210Pb and 137Cs in the sedimentation rate of the lagoons of the Nile Delta. At the same time, some suggestions were also proposed by the author in the aspects of borehole location, lithology, sampling interval, calculation model, etc. In this paper it is supposed to help better understand the lake sedimentation processes and lake pollution history under the influence of intense human activities. |
