内蒙古风沙草原区地球化学元素表生垂向迁移规律研究内蒙古风沙草原区地球化学元素表生垂向迁移规律研究

摘要：本文主要研究了内蒙古风沙草原区底部土壤中地球化学元素的分布规律及其垂向迁移规律。通过采集不同深度的土壤样品，分析样品中的地球化学元素含量，可以看出研究区地下水对土壤地球化学元素分布具有很大的影响，底部土壤中Al、Fe等元素含量较高，同时还发现底部土壤中重金属元素含量也相对较高。分析发现，尽管研究区降水量较少，但是在风吹沙移的过程中，底部土壤会持续受到重力及水流的影响，导致地球化学元素的垂向迁移。实验结果表明，该区域的土壤层次与地球化学元素的分布较为复杂。通过分析不同深度土壤中的元素分布情况，发现底层土壤中Al、Fe、Mn等元素含量较高，对人体健康可能会造成潜在的威胁。
