[0002] Desertification is one of the prominent global ecological and environmental problems, gradually threatening human survival and sustainable economic and social development. How to effectively prevent desertification has become a top priority. Laying grass grids is the most effective method in engineering sand fixation that has been proven in practice. It can play a dual role of preventing wind and sand and conserving water. Reeds are widely distributed and their stems are rich in cellulose. Mature reed straw has the advantages of high hardness and strong toughness. The grass grids made from it have broad market potential and good ecological benefits.
