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。

Under optical microscope,the observational result indicates that the peach blossom stone samples from Gao Mountain contains transparent and distransparent minerals which forms pealike and red spots.

光学显微镜的观察结果表明，高山桃花石样品中存在透明和不透明矿物，其中不透明矿物形成了艳丽的红色斑点；XRD测试表明，样品的矿物组成为地开石、赤铁矿、石英以及少量的叶腊石；拉曼光谱测试结果表明，样品的基质部分为地开石，结晶形态完好的红色矿物颗粒与呈浸染状的红色部分均为赤铁矿，无色透明的矿物颗粒为石英。

Under optical microscope, the observational result indicates that the peach blossom stone samples from Gao Mountain contains transparent and distransparent minerals which forms pealike and red spots. The XRD testing result indicates that the mineral compositions in the samples are dickite, hematite, quartz and a little pyrophyllite. LRM testing result shows that the basic part of the samples is dickite, the red minerals with both well crystal shape and dip dye shape are hematite, and colourless and transparent mineral grains are quartz.
