| Abstract: | In order to explore the sand fixation effectiveness and service life of polylacticacid sand barriers,polylacticacid sand barriers were taken on the shifting sand dunes in the desertified rangeland with a high altitude in Maqu County,and the aging test was conducted in Key Laboratory of Desert and Desertification.The results showed that the polylacticacid sand barriers were effective in radiation resistance,aging resistance and sand fixation. |
