沙尘暴是因为环境被破坏引起的，它的形成与地球温室效应、厄尔尼诺现象有着不可分割的关系。植被破坏、森林锐减、物种灭决导致气候异常。沙尘暴的危害很大，沙尘暴来临的时候，可能会引诱人的过敏性疾病、流行病及传染病。即使是身体健康的人，如果长时间吸入沙尘，也会出现咳嗽、气喘等多种不适症状，导致流行病发作。
The hazards, and its harm sandstorm way generally can be classified into four types: sand buried, wind, wind and atmospheric pollution environment.

Sand Storm
I come from Inner Mongolia.My hometown suffered from sand storm seriously.sand storm is really terrible:when it comes, the sky will probably turn yellow and in contrast all the lightening bars' color turn into blue.Strong wind will follow, all the people will hurry home.If you stand in the wind for 3minutes, your hair will need 3time-wash after the disaster!How awful it is!
The cause for it is the over-herding,which make the grass land into desert.sand storm can do great harm to the live stock of the farms,it can spread desert and kill cattle,making the traffic disabled,the invisibility let the planes cancelled.What' more, plants in the farmland will be buried,food supply will lose.
There are some way to prevent it from happening:
Plant grass and tress according to the topography;set limit to herding;search for International backup.Here
is a good news for it.China, Korea,Mongolia and Japan will cooperate to father sand storm On May.29, in the conference " International conference of Women and prevention and fathering work for desertification" held in Beijing, the director for sand storm prevention office of State forestry administration, Liu Tuo said that China, Korea, Mongolia and Japan have constituted the general layout for fathering the sand storm in order to meet the harm by it.
沙尘暴的形成需具备4个条件。
一是地面上的沙尘物质。它是形成沙尘暴的物质基础。
二是大风。这是沙尘暴形成的动力基础，也是沙尘暴能够长距离输送的动力保证。
三是不稳定的空气状态。这是重要的局地热力条件。沙尘暴多发生于午后傍晚说明了局地热力条件的重要性。
四是干旱的气候环境。沙尘暴多发生于北方的春季，而且降雨后一段时间内不会发生沙尘暴是很好的证据。
春季沙漠的边缘地区，由于长期干旱，而且地表少有植被覆盖，当有大风来临的时候地表的沙尘很容易被吹起且被输移，但由于沙子粒径较大，不易形成悬移(悬浮移动，是小颗粒物质保证长距离输移的必要条件)，因此不能长距离输移，这也是距沙尘较远的地区只有降尘而少见扬沙的主要原因。如果风持续的时间很长，形成悬移的浮尘能够被输送到很远的地方，所经过的地区就会出现沙尘暴；当风速减弱到一定程度后，浮尘就会降落，该地就会出现降尘天气。如果此时降水，就会形成所谓的“泥雨”。
从沙尘暴形成过程所需的4个条件看，黄土高原、广袤的沙漠及由人为因素的破坏正处于荒漠化过程中的土地，北方春季末耕种的土地及处于施工过程中的基础设施(如高速公路等)为沙尘暴的发生提供了充分的物质源；而春季北方地区的干旱，又使沙尘暴发生的可能性增强；大风的产生是一种复杂的大气现象，主要是冷锋活动或经纬向环流调整作用的结果。
