摘要
通过对 1 992年 4月 1 0～ 1 4日在常州和 1 998年 4月 1 4～ 1 7日在西安及南京两次沙尘和天气过程的分析 ,叙述了沙尘和非沙尘总悬浮颗粒物化学特性的差异。通过与各类土壤化学特性比较以及沙尘发生期的天气背景分析 ,指出了两次沙尘的可能源地和利用化学元素平衡法定量地求出西北土壤源在沙尘中的贡献率。
The proceedings and meteorological background of two duststorms happened in Changzhou on 10～14th April 1992 and in Xi'an on 14～17th April 1998 were discussed. The results show that there are chemical characteristic differences between the duststorm and non duststorm proceeds. By comparison with the characteristics of some kinds of soils, we came to know the possible origin of the duststorm and the distributions of soil source to the duststorm were accounted.
