Desertification in Northwest Shanxi Province

Miao Aimei, a senior engineer of Shanxi Meteorological Observatory, said that in the past 20 years, the sandstorm weather process in Shanxi Province has been decreasing year by year, with a slight rebound in 2000, and there were 8 large-scale sandstorms. From last year to now, the influence of sandstorms in Shanxi has also shown signs of weakening, but the situation is still not optimistic, especially in northwest Shanxi, where desertification is serious and ecology is fragile. It is very important to prevent wind and sand and restore ecology.

Shanxi is located in the front of desertification expansion, and the daily trend of land desertification in northwest Shanxi is serious, which belongs to the high incidence area of sandstorm. As we all know, there is a wind every year. From spring to winter, there is no wind for three feet and the wind is full of soil. These are mainly distributed in 16 counties (districts) in Datong, Shuozhou and Xinzhou, and the area of land desertification is increasing every year. The old city of Youyu County 12 meter high wall has now been buried by yellow sand, and people can directly climb the wall along the slope; Many villages in Wuzhai County were forced to move every twenty or thirty years because of sandstorms, which became the biggest enemy of local people. Due to the harsh climate and scarce vegetation, the strong monsoon from Siberia blew the local chestnut soil into the air through Datong and Shuozhou areas, and blew it to Hebei Plain and Beijing-Tianjin areas.
