Sandstorms swept the Hexi Corridor like dark clouds. How to prevent sandstorm weather?

Today, let's talk about how to prevent dust weather.

Sandstorm weather is a kind of disastrous weather and meteorology formed by the interaction of wind and sand. Sandstorm weather can't happen in windy places. Generally, it only happens in some areas with sparse vegetation, serious desertification and dry climate. Then, in the case of strong winds, the sand on the bare land is easily blown up by strong winds to form sandstorms, even strong sandstorms.

Sandstorms also have a great impact on the environment, causing air pollution and topsoil loss. Sandstorm weather will cause very serious harm to the soil and atmospheric environment and agricultural production in the producing area and surrounding areas, and the wind will blow away the topsoil, which will seriously lead to crop yield reduction.

Moreover, when sandstorms occur, if people are exposed to dusty weather, then all kinds of toxic chemicals, bacteria and other dust will enter people's respiratory tract, and these harmful substances and bacteria will infringe on people's health, thus causing many respiratory diseases.

When a sandstorm occurs, it will also seriously affect our traffic safety. Because sandstorms and weather reduce visibility, it will greatly increase the probability of traffic accidents such as trains, cars and planes.

So how should sandstorms be prevented?

First of all, we should strengthen human protection of the environment, raise environmental protection to the height of the rule of law and restore vegetation greening. It is also necessary to strengthen the biological protection system for preventing sandstorms in the morning paper, protect and restore forest and grass vegetation according to law, prevent the land desert from expanding further, and minimize the sources of sandstorms.

According to different regions, formulate disaster relief and prevention plans according to local conditions, actively promote various disaster reduction technologies, build model projects, and then gradually promote them from point to area to further improve the regional comprehensive defense system.

In addition, it is necessary to control population growth, reduce the pressure of human factors on the land, protect the environment, strengthen popular science propaganda on the relationship between sandstorms and human activities, and let people clearly understand the living environment. If it is destroyed, it will be difficult to recover, which will not only aggravate natural disasters such as sandstorms, but also cause a vicious circle. Therefore, we humans must consciously protect our living environment.

In addition, plants suitable for growing in desert areas, such as Hippophae rhamnoides, should be planted to form a ground cover layer, thus improving the environment, reducing wind speed, increasing air humidity, fixing soil and improving microclimate environment.

You can also plant small trees and low shrubs of native varieties on the edge of the desert to improve the distribution of vegetation.
