摘　　要：枯落物分解是影响湿地生态系统物质循环和全球气候变化的关键过程之一.为了全面了解湿地枯落物分解的发展趋势和研究热点,使用Web of Science(WOS)数据库,通过文献计量学软件CiteSpace,对相关内容进行可视化分析.同时,梳理湿地枯落物分解的研究进展;归纳湿地枯落物的分解过程、影响机制和研究方法;提出相关领域的研究展望.结果显示:湿地枯落物研究分为缓慢-平稳-快速增长3个阶段,研究核心内容包括植物群落多样性、微生物驱动机制、枯落物性质、全球气候变化、碳循环等.同时,枯落物分解主要受到生物和非生物因素的影响,其中土壤微生物及相关酶活性是影响枯落物分解的初始限制性因子;研究方法以室内培养法及野外分解袋法为主.综上,现在湿地枯落物分解研究仍处于快速发展阶段,尽管从植物、土壤和微生物各因素上进行了较多探讨,但受限于以往研究手段,科学界对枯落物分解的影响机制,特别是各因素间的相互作用机制还缺乏系统了解.因此,未来研究亟需提出新的枯落物分解研究方法,重点关注植物-土壤-微生物间复杂的相互作用关系,为湿地枯落物研究乃至土壤碳循环研究提供重要理论支撑.Litter breakdown is one of the key factors that control the nutrient cycle and global climate change in wetlandecosystems. To understand the research advances and hotspots about litter breakdown in wetlands, we utilized thebibliometrics software, named as CiteSpace, to visualize the searched results and further systematically summarizethe research progress (i.e. decomposition processes, mechanisms, and methods) about litter breakdown based onWeb of Science. Our results showed that studies about litter breakdown had three developmental stages, slow-stablerapidgrowth, and the key research included plant composition diversity, microbial mechanism, litter quality, globalclimate change, and the carbon cycle. More importantly, litter breakdown is affected by several biotic and abioticfactors, soil microbial community and its related soil enzyme activity is the initial limiting factor influencing litterdecomposition processes. The methods to estimate the litter breakdown are usually used for laboratory incubationand litterbag technique. In conclusion, the research on litter breakdown in the wetland is still in the rapiddevelopment stage, and several factors, i.e. plant, soil, and microbes, had been discussed to affect litter breakdown.However, due to the methods through previous studies, a systematic understanding of the mechanism of litterbreakdown is still not clear, especially the plant-soil-microbe interactions. Thus, future research needs to develop astandardized method to explore the interaction effects and try to provide an important theoretical basis for litterbreakdown studies and carbon cycling in wetland ecosystems.
