Land degradation poses a severe threat to global ecological security, and traditional wind erosion control technologies face limitations in durability and environmental compatibility.Microbially Induced Calcium Carbonate Precipitation (MICP) has emerged as a sustainable sand stabilization approach, demonstrating significant effectiveness in enhancing the wind erosion resistance of sandy soils.However, the practical implementation of this technology still faces challenges, including high costs, uneven cementation, and environmental risks associated with NH 4 + release.This study reviews the latest advancements in MICP technology, focusing on cost optimization, field applications, and byproduct management.Research indicates that selecting native microbial strains, utilizing waste resources (such as human urine and eggshells) as substitutes for industrial reagents, and optimizing processing techniques can significantly reduce MICP treatment costs.Field experiments have confirmed that MICP enhances soil stability and can be integrated with physical sand barriers to improve sand stabilization effectiveness.To address the issue of NH 4 + byproducts, strategies such as struvite precipitation and zeolite adsorption have proven to be effective in achieving efficient removal.Future research should focus on long-term durability, adaptation to extreme climatic conditions, and the resource utilization of byproducts to facilitate the large-scale application of MICP technology.
