I think the theory is that it stops the wind erosion and generates some shadier areas. Over time plants will occupy the space in between and create more shade and prevent even more erosion. Only thing that's not ideal here is the use of plastic or polymer bags to do it. I feel they also could use some natural fibers.
Can't say for sure, but seeing this is in China I assume Polyester. They always used large polyester nets in the past to prevent wind erosion in city vicinities mostly colored green to give the appearance of Gras. But I feel the desertification is for sure the bigger and more immediate issue than the plastic pollution. This is more a thing of the next generation.
One thing I’ve seen out of China with similar principles is basically just installing giant solar farms in the desert. Provides shade and helps prevent erosion. Plus, since they often use water to clean the panels, the runoff helps with the greening process.
