摘　　要：为探究园林绿化垃圾堆肥促腐减排的优化策略,以中国学术期刊网络出版总库(CNKI)和Web of Science核心合集数据库为研究基础,对园林绿化垃圾堆肥的相关文献进行梳理和总结,探讨了园林绿化垃圾的时空特征、理化特性及其堆肥技术面临的挑战,并从园林绿化垃圾的预处理方法、堆肥物料营养结构调控、堆肥菌群功能调控及堆肥工程工艺参数优化等方面,综述了园林绿化垃圾堆肥增效促腐与提质减排的优化策略。结果表明:园林绿化垃圾堆肥时,应根据原料特性、操作成本和堆肥应用场景等因素选用合适的预处理手段或物料调配策略,接种特定功能微生物并优化微生物菌剂接种手段,合理选用堆肥工程工艺技术,以加快堆肥腐殖化进程,减少恶臭气体排放。为今后园林绿化垃圾高温好氧堆肥技术的创新提出了研发攻关方向,以期加快园林绿化垃圾快速降解技术的提升,为我国城市园林绿化垃圾处理和资源化利用试点建设提供支撑。Composting is one of the important ways to promote the construction of the technical system of harmless treatment and recycling of urban green waste.In order to explore the optimization strategies for promoting decay and reducing emission of green waste composting,based on CNKI and Web of Science Core Database,the literature related to green waste composting was sorted and summarized.The spatial and temporal characteristics,physical and chemical properties of green waste and the challenges of composting technology were discussed.Meanwhile,from the aspects of pretreatment method of green waste,nutrient structure of compost materials,regulation of bacterial community function and optimization of compost engineering parameters,the optimization strategies of green waste composting were summarized.The results showed that:Suitable pretreatment methods or material allocation strategies should be selected according to multiple factors such as raw material characteristics,operating cost and composting application scenarios.It is necessary to inoculate specific functional microorganisms and optimize microbial inoculant methods with reasonable selections of composting engineering technology to promote compost humification process and reduce odor gas emission.In order to accelerate the rapid degradation technology of green waste,and provide support for the pilot construction of urban green waste treatment and resource utilization,the research direction of high temperature aerobic composting technology for green waste is proposed in the end.
