| 摘 要： | 以近年来我国西北地区多发的沙尘暴现象为缘起,对沙尘暴的特征、发生机制等进行了讨论;论述了沙尘暴引起的降尘与黄土的堆积与沉积的过程;黄土堆积沉积的年龄、颗粒成分等;以及沙尘暴与高土高原的形成之间的关系,同时论述了黄土高原的环境变迁,认为高空均质粉尘的降落是不均匀的;高空降尘是突发的,而风及流水对堆积粉尘的改造是长期和连续的。

| Abstract: | Taking the dust storm phenomenon occurred in recent years as an excuse, the characteristic and regulation of dust storm are discussed. Then the loess deposit, vegetation vicissitude the relationship between dust storm and formation of the Loess Plateau are also discussed. Some results are: the falling of the even dust in the sky from the remote west is not even; the occurrence of dust storm is abrupt, and the effect of runoff and wind to loess deposit is continuous and lasting. |
