Gansu is located in the intersection point of loess plateau monsoon region, arid area of Mongolian Plateau and cold area of Qinghai Tibet Plateau, with sensitive climate and fragile ecological environment. The desertification land area is 195 thousand square kilometers and the work of prevention and control of desertification are very important.

Gansu Sandification Control Research Institute and Minqin Sandification Control Experimental Station have invented 6 new sand barriers, including the clay+ Haloxylon sand barrier, cotton stalk fence sand barrier, sand fixing shrub, and sand grid simulation. 18 new sand barriers were introduced, such as straw checkboard sand barrier, plastic mesh sand barrier, etc. to solve the problems met in the traditional sandification control process such as short life-circle, lack of materials, and high costs.. In recent years, Gansu Sandification Control Research Institute has established 10 sandification control models in Minqin, Linze, Gaotai, Gulang, Guazhou, Jingtai County through the promotion of using new materials and technology, including straw checkerboard barrier+ Haloxylon afforestation. The promoted area researches 5.3 million mu, controlled area researches 3.2 million mu and the protected farmland researches 46.2 million mu in northern China.
