With the intensification of global climate change and the worsening of land degradation, desertification has emerged as a significant global issue threatening ecosystems and human activities. The technique of Microbial Induced Calcium Carbonate Precipitation (MICP) has been widely applied in soil stabilization and engineering geology in recent years. This study conducts experiments using Bacillus megaterium to solidify desert sand via MICP, aiming to explore its feasibility as a novel ecological method for desert protection. Experimental results indicate that desert sand treated with MICP exhibits a significant enhancement in wind erosion resistance, providing a potential solution for desert management and land restoration.
