Based on this idea, the author has chosen two typical loess sections of Luochuan, and Xifeng for this study, collected the successive loess columns; To probe the conditional experiments of BeO sample preparation and measurement, and improve the existing method; On the basis of the technology improvement, the author has finished 402 samples' BeO preparation and AMS measurement; Also at the same time, to separate quartz from samples at 1 cm interval for both Luochuan and Xifeng sections systematically, to carry out measurements of quartz grain-size, SUS, grey scale, carbonate content and bulk sample density; By using the grain size model, the author has set up the chronological framework for both Luochuan, and Xifeng sections and the time sequence of millennial scale abrupt climate events recorded in loess strata, and reconstructed the East Asian monsoon history over 130ka by using multi proxies; Finally, to discuss the possible mechanisms of palaeoclimatic changes tentatively.
详细地球科学的发展离不开高精度和高分辨率的研究。运用长寿命核素如〓Be作为环境过程的示踪,已成为不可替代的有效工具。本论文选择洛川、西峰两个典型的黄土剖面,连续采集柱状样;探索了BeO样品制备、测量的条件实验,改进了原有的方法,完成了402个BeO样品的制备和AMS测量;同时还系统地分离洛川、西峰剖面高分辨率(1cm)黄土、古土壤样品中的碎屑石英,测量了碎屑石英粒度,以及全样的磁化率、灰度、碳酸盐含量和容重等古气候代用指标;采用粒度年代模式建立了洛川剖面和西峰剖面的年代标尺,建立了黄土地层记录的千年尺度的气候突变事件的时间序列,多指标重建了最近130ka东亚季风变迁史;初步讨论了古气候变迁的可能机制。

A 50-year Porites lutea core from Nansha Islands (9°33′N, 112°54′E) was analyzed for δ〓O and δ〓C for two aims. First, we hope to find and set up some formula between δ〓O and environmental parameters, such as thermometer readings, so that we can reconstruct historical environment of this area. Second, we hope to understand the climate changing process during the past fifty years of this area and its relation to the global change.
本文以南沙群岛永暑礁的滨珊瑚Porites lutea为研究对象,通过质谱分析,研究珊瑚月分辨率δ〓O、δ〓C记录的环境信息,旨在为进一步重建南沙群岛过去高分辨率的环境变化提供一个类似于温度计的标尺;还重建了永暑礁器测时期以前40年高分辨率的环境变化过程,旨在了解南沙群岛气候变化过程及其与全球变化的关系。
