Twenty counties (cities and districts) in the western and northwestern Liaoning provinces are listed as key areas for the construction of the Three North Shelterbelt system in the country. In this narrow strip of more than 500 km long and 150 km wide in both north and south, the area known as “Jinchifeng and Silver Chaoyang” has become an area characterized by sparse forest vegetation and ecological environment due to the serious damage in the recent century. Extremely bad place is the area with the largest sandstorm and the most serious hazard in our province. There are few windless days throughout the year, and the wind speed is high and the frequency is high. The average wind speed is 3.3m / s and the extreme maximum wind speed can reach 38.3m / s . The northwestern region of our province is located in Horqin Sandy Land
