What measures have been taken against soil desertification in northwest China?

There will still be wind and bitterness in spring, but there is no yellow sand all over the sky and no sand hitting the face. What happened in the past ten years. Divided into two parts:

1: remediation measures in non-desert areas: in chronological order: returning grazing to grassland-returning farmland to forests-Beijing-Tianjin-Hebei sand control project-ecological migration. Everyone knows that this is government-led and the policies are consistent.

2. Restoration measures in desert areas: International friends: Japanese. Whether it is Toyama Seiko in Kubuqi Desert or Japanese sprinklers in non-desert areas. It has indeed made great contributions to improving the ecological environment. Local government: In the 1990s when the Yellow Sand was raging, the local government began to realize the environmental problems and began to plant trees on a large scale. In primary and secondary schools, the school organizes planting trees with dry food and water on Arbor Day. The school has never been organized since high school, because the ecology has been controlled. NGOs: private enterprises and voluntary non-profit organizations. Let me talk about the contribution of a private enterprise that I know better to Kubuqi Desert and desertification. Everyone knows the Baoning Railway. But few people know that Kubuqi crossed the sand road. The same construction mode, the same construction suffering. The only difference is that the Baoning Railway is a government project, while the sand-crossing highway is a private project. The sand-fixing car created by China is 50 times more efficient than manual mowing! The plaid material can be grass, and I think it can also be industrial fiber (there is fiber grass plaid now). Of course, grass is the best, which is economical and environmentally friendly. If fibers are used, degradation must be considered. The problem of grass is that the supply chain of technology and materials for mass production of grass curtains should be stable. Maybe in the future, we can plan to support wars by fighting, that is, planting grass in the desert, making grass curtains, and then transforming the desert. This is a virtuous circle. Considering that grass may be a water-consuming crop, it may also be developed in other areas where there is no water shortage.
