【摘要】 荒漠化严重影响社会经济发展和生态环境，亟需经济且高效的荒漠化防治方案。农林剩余物作为一种价格低廉、容易获取的可再生资源，在沙漠治理中展示出了较大潜在应用价值。为解析农林剩余物在固沙改土中的资源化应用研究进展，从资源特性、防风固沙、土壤改良三个维度展开论述，梳理了农林剩余物的应用优势，综述了农林剩余物在荒漠化防治中资源化应用的研究进展，详细阐述了其固沙改土的作用机制与技术路径，并结合目前的研究现状对今后研究提出了建议，以期为农林剩余物在固沙改土方面的应用研究提供参考。更多还原

【Abstract】 Desertification severely impacts socio-economic development and ecological environments, making economic and efficient desertification control solutions urgently needed. Agricultural and forestry residues, as low-cost and easily accessible renewable resources, have demonstrated significant potential application value in desert management. In this paper, the research progress on the resource utilization of agricultural and forestry residues in sand fixation and soil improvement was analyzed. The discussion was conducted from three dimensions: resource characteristics, windbreak and sand fixation, and soil improvement. The application advantages of agricultural and forestry residues were summarized, the research progress on their resource utilization in desertification control was reviewed, the mechanisms of action and technical pathways for sand fixation and soil improvement were elaborated in detail, and recommendations for future research were proposed based on the current research status, so as to provide references for the application research of agricultural and forestry residues in sand fixation and soil improvement.更多还原
