摘要
本文对喀喇昆仑山-西昆仑山地区土壤中23种元素的自然含量进行了论证。用对比和区域分异系数的方法,讨论了本区土壤元素在世界、我国和区域内的异同和分异特征。通过相关分析和主成份分析,揭示了土壤元素的共生组合关系和表现在土壤类型上的聚类特征,进一步说明了元素在本区土壤中的相关性和分异特征。
Natural contents of 23 elements in soils of Karakoram and West-Kunlun Mountains of Qinghai-Tibet Plateau are demonstrated in this paper. The characteristics of regional difference of soil elements in this region, the world and China are discussed using contrating and regional differential coefficient methods. Through correlation and principal component analysis, the relationship of intergrowth and association among soil elements and the cluster characteristics manifesting in soil types are revealed, and the correlation and differential characteristics of elements in soils of this region are further explained.
