摘要
民和黄土各粒径组分含量变化与磁化率曲线对比，并进行相关分析发现：民和黄土＞３０μｍ的粗颗粒组分可以作为较敏感的东亚冬季风代用指标。明确了民和黄土粗颗粒组分与气候变化的良好对应关系。
Comparison between the granulometric composition and the magnetic susceptibility curve of the Minhe loess and correlation analysis have revealed that the >30μm coarse grain component can be used as a sensible index for the East Asian winter wind. This paper has established a good correlation between the coarse grain component of the Minhe loess and the change of climate
