随着城市绿化面积的增多,园林废弃物也同步增多,园林废弃物堆肥化处理是近年来研究的热点.为了掌握并深入分析该领域的研究现状和趋势,探析未来的研究发展方向,以中国知网(CNKI)数据库以及Web of Science TM(WOS)核心文献数据库的文献资料为数据源,借助文献信息可视化分析软件CiteSpace,对历年有关园林废弃物堆肥研究领域的相关文献从年度分布、研究主体(国家、机构、期刊、作者)和关键词及高被引论文方面进行分析.结果显示:①国内外年度发文量呈明显上升趋势,表现为探索阶段—稳步增长阶段—快速发展阶段.②美国的发文量、中心性、被引频次和h指数综合排名第一.③北京林业大学在国内外发文量位居第一.④期刊排名看,国内《中国园林》以发文量、被引频次和篇均被引频次排名第一,国外Bioresource Technology以发文量、被引频次和篇均被引频次排名第一.⑤国内外发文量前10 的学者都来自北京林业大学,其中孙向阳的国内外发文量排名第一.⑥国内研究热点为园林废弃物结合厨余垃圾、淤泥污水堆肥和栽培基质,国外研究热点为园林废弃物堆肥结合污水淤泥和猪粪作为土壤改良剂,降低土壤重金属等方面的研究.⑦国内学者主要对园林废弃物堆肥发展前景进行综述,部分学者对园林废弃物堆肥过程理化性质变化研究和施用园林废弃物堆肥对土壤的影响进行研究,而国外学者大多数是针对园林废弃物堆肥对土壤养分、酶活性、微生物量和减少土壤重金属含量进行研究.总体而言,北京林业大学的文章总数最多,对园林废弃物堆肥领域贡献最大;我国学者在外文文献中发文数量、论文被引频次方面都占据重要地位,表明我国在该研究领域有着较强的国际学术影响力;但是根据热频关键词可以看出,国外学者对于园林废弃物堆肥方向研究较多.
Visual Analysis of the Research Progress of Garden Waste Composting Based on CiteSpace at Home and Abroad
With the continuous expansion of urban greening,along with the production of a large number of garden waste,garden waste com-post treatment is also a research hotspot in recent years.In order to grasp and in-depth analysis of the research status and trend in this field,ex-plore the future research and development direction.With the literature data of CNKI database and Web of Science TM(WOS)core literature database as the data source,and with the help of the literature information visualization analysis software CiteSpace,the literature related to the research field of garden waste composting over the years was analyzed from the aspects of annual distribution,research subjects(countries,in-stitutions,journals,authors),keywords and highly cited papers.The results showed that:①The number of annual publications at home and a-broad showed an obvious upward trend,which showed an exploration stage-a steady growth stage-a rapid development stage.②The United States ranked first in the number of publications,centrality,citation frequency and h-factor.③Beijing Forestry University ranks first in the num-ber of publications published at home and abroad.④The domestic"Chinese Landscape Architecture"ranked first in terms of number of articles published,citation frequency and citation frequency per article,while the foreign Bioresource Technology ranked first in terms of number of arti-cles published,citation frequency and citation frequency per article.⑤The top 10 scholars with the most published articles at home and abroad are all from Beijing Forestry University,among which Sun Xiangyang ranks first in the number of published articles at home and abroad.⑥Do-mestic research hotspots are garden waste combined with kitchen waste and silt sewage compost and cultivation matrix,while foreign research hotspots are garden waste compost combined with sewage sludge and pig manure as soil amendment to reduce soil heavy metals.⑦For domestic scholars mainly of garden waste composting development prospect were reviewed,some scholars studying the physical and chemical properties change of garden waste composting process and application of garden waste compost on soil were studied,the influence of the foreign scholars mostly in view of the garden waste compost on soil nutrients,enzyme activities,microbial quantity and reduce soil heavy metal content were studied.In general,Beijing Forestry University has the largest number of articles,which contributes the most to the field of garden waste compos-ting.Chinese scholars have an important position in the number of publications and citation frequency of papers in foreign literatures,indicating that China has a strong international academic influence in this research field.However,according to the keywords of thermal frequency,foreign scholars have more research directions for garden waste composting.
