摘　　要：全国每年产生7000万~10000万t园林绿化废弃物,数量巨大,并呈现逐年增长趋势。在“双碳”战略背景下,为实现城市绿色低碳可持续发展,需要对园林绿化废弃物进行科学处置利用,实现其减量化、无害化和资源化利用,“变废为宝”,缓解城市有机固体废弃物的处置压力。系统总结和探讨了覆盖物化、堆肥化、养料化、材料化、固体燃料化、生物燃气化、热解多联产、景观化等绿色资源化利用研究进展,并对今后的发展趋势进行了展望,以期为加快实现园林绿化废弃物绿色低碳利用提供参考。China generates 70-100 million tons of garden waste per year,with an enormous amount and shows a trend of expanding year by year.Under the background of the“double carbon”strategy,in order to achieve green and low-carbon development of the city,it is necessary to scientific disposal and utilize garden waste,to achieve its reduction,harmlessness and resourcefulness,to“turn waste into treasure”,and to alleviate the pressure of urban organic solid waste disposal.This paper summarizes and discusses the research progress of greening resource utilization such as mulching,composting,nutrient conversion,materialization,solid fuel conversion,bio-gasification,pyrolysis multi-coupling and landscaping,and provides an outlook on the future development trend.It is expected to provide reference for accelerating the realization of green and low-carbon resource utilization of garden waste.
