The sandstorm is a general name of sandstorm and dust storm, and the sandstorm is a weather phenomenon that the ground dust is blown up by strong wind to make the air very turbid and the horizontal visibility is less than 1km, and is a main sign of desertification. According to the records of historical materials, in 2154 years of 3 century-1949 before the Yuan, the sand storm occurs 70 times in China, and occurs once in 31 years on average, but the occurrence frequency of the sand storm in China is rapidly increased since 50 years of the 20 th century, and the sand storm in China gradually has a new trend of early occurrence time, large influence range and the like. At present, the spatial law of sand storm occurrence in China is that the west is more than the east, the north is more than the south, the space law is mainly concentrated in arid and semiarid regions in the northwest and the north of China, the sand storm occurs all the year round in the occurrence time, and the statistics of records of the sand storm carried with months according to 494 cases of China show that the sand storm mainly occurs in 2-5 months and accounts for 78.3% of the total number, wherein the sand storm is most frequent in 3-4 months and accounts for 49.2% of the total number, and the sand storm occurs in 2 months and 5 months, and other months are fewer.

The formation of a sandstorm requires these three conditions: the first is the sand and dust matter on the ground, which is the material basis for forming the sand and dust storm; the strong wind is a power foundation formed by the sand storm and also a power guarantee that the sand storm can be conveyed for a long distance; three are unstable air conditions, which are important local thermodynamic conditions.

The main hazards of sand storms are embodied in the following aspects: 1) causing environmental pollution and worsening of ecological environment; 2) production and life are affected; 3) loss of life and property; 4) traffic safety is affected; 5) the health of human body is harmed; 6) the land is degenerated, so that a method for preventing and treating desert sand storm, which is simple and easy to implement, convenient to popularize, quick in effect taking and relatively low in cost, is urgently needed.
