沙生灌木基生物质材料研究进展与发展趋势

Research progress and development trend of sandy shrub-based biomass materials

沙生灌木是我国西部干旱、半干旱地区丰富的生物质资源,以其抗旱、抗寒、生长快等优点在防风固沙和水土保持方面对生态保护与荒漠化治理具有重要意义。基于此,围绕沙生灌木资源的生物质资源属性,系统总结了近年来沙生灌木资源在木质复合材料、生物质活性炭材料、木质资源液化物和生物质炭材料等领域的研发现状。结果表明,现有丰富的研究成果已充分证实了沙生灌木资源在上述生物质材料领域应用的巨大潜力。然而在纳米纤维素、生物质炭材料等领域尚存在研究成果不够丰富、研发技术不够成熟,相关技术水平不够先进的现实问题。最后,在拓宽沙生灌木资源种类、提升沙生灌木基生物质材料附加值以及加大沙生灌木基生物质材料高附加值关键科学技术转化进程等方面提出了研究展望,旨在为进一步提高沙生灌木资源的高效利用提供科学依据。

Sandy shrubs are abundant biomass resources in the arid and semi-arid areas of Western China.With their advantages of drought resistance,cold resistance and fast growth,they are of great significance to ecological protection and desertification control in windbreak,sand fixation and water and soil conservation.Based on this,the paper systematically summarized the research and development status of sandy shrub resources in the fields of wood composite materials,biomass activated carbon materials,liquefied wood resources and biomass carbon materials in recent years around the biomass resource attribute of sandy shrub resources.The results showed that the existing abundant research results had fully confirmed the great potential of sandy shrub resources in the field of biomass materials.However,in the fields of nanocellulose and biomass carbon materials,there were still practical problems such as insufficient research results,immature R&D technology and insufficient advanced technology level.Finally,research prospects were put forward in terms of expanding the types of sandy shrub resources,improving the added value of sandy shrub-based biomass materials and accelerating the transformation process of key science and technology with high added value of sandy shrub-based biomass materials,aiming to provide scientific basis for further improving the efficient utilization of sandy shrub resources.
