| 摘 要： | 本文较详细地介绍和论述了土壤年代学方法及其测年原理，以及该方法的国内外研究现状和发展应用前景．作者将该方法的基本思路引入榆木山和阿尔金山山前地区的活动构造测年工作，并初步建立了土壤ＣａＯ、ＣａＣＯ３和ＣａＣＯ３累积指数值与发育年代之间的定量计算关系式，统计得到了土壤中砾石钙膜的平均累积速率．通过回检和应用对比分析，认为土壤年代学方法适用于中国西北地区，并具有广阔的应用前景．

| Abstract: | In this paper,the soil chronological method and its dating principle as well as present research situation at home and abroad and developmental prospect for application are introduced and discussed in detail.The fundamental train of thought of this method has been applied by the authors to dating study of the foreland regions of the Yumushan mountain and Altun mountain,and four quantitative relational expressions between CaO,CaCO 3 content and CaCO 3 accumulation index value in soils and their developmental age have been preliminarily formed and the mean accumulation rate of the calcic coats on gravels in soils has been obtained by statistical calculation as well.Through test and comparative analysis,it is considered that the soils chronological method is applicable to the Northwestern region of China and has the vast prospects for application. |
