摘要
通过对西安市降尘的成分和元素含量的分析，并与本区沉积于１．８万ａ前（那时还没有现代化工业）的晚更新马兰黄土的元素含量相比较，对西安市降尘的元素特征和变化进行了研究，同时也探讨了降尘的来源以及空气的污染程度和污染源。
Based on the analysis of the compositon and the element content of dust fall in Xi'an urban area and in constrast with the element content of the Malan loess depositted 18 000 yeas ago,and at that time there was no modernizing industry,the element characteristics and variations of the dust fall are studied. Meantime,the degree of pollution and pollution source of the air as well as source of dust fall are also investigated.
