摘要
森林凋落物分解不仅会产生养分维持森林生态系统肥力和生产力,成为森林生态系统重要的养分来源,还会产生CO_(2),从而影响全球生态系统碳循环。近些年来,由于人们工业活动的发展,人们向大气中排放的含氮化合物增加,而氮沉降对凋落物分解的影响研究结果不一。为此,采用2种可视化软件VOSviewer和CiteSpace基于WOS数据库和CNKI数据库对该领域文献进行了计量分析,结果表明:未来的研究方向,主要存在3个新的研究趋势:①形成了多个条件,多个研究内容的研究;②主要集中于土壤动物、微生物及相关酶活性和土壤有机质的研究;③温带、寒温带森林研究成为新的研究对象。
Forest litter decomposition not only produces nutrients to maintain the fertility and productivity of forest ecosystems,but also becomes an important nutrient source for forest ecosystems.It also produces CO_(2),which affects the global ecosystem carbon cycle.In recent years,due to the development of people's industrial activities,the emission of nitrogen compounds to the atmosphere has increased,and the effects of nitrogen deposition on litter decomposition have been studied.In this study,two visualization software VOSviewer and CiteSpace were used to analyze the literature in this field based on WOS database and CNKI database.The results show that in the future research direction,three new research trends have been formed:①multiple conditions and multiple research contents are formed;②soil animals,microorganisms and related enzyme activity and soil organic matter are mainly focused on;③temperate and cold temperate forest research has become a new research object.
