| 摘要: |
| 【目的】绿肥对于改善因化肥过量施用导致的农业面源污染、土壤温室效应等问题具有重要实际意义。本文以探究绿肥施用对农田温室气体排放的影响为主题，旨在推动绿肥施用技术研究领域的发展。【方法】以Web of Science核心合集数据库为基础，借助Origin等统计软件，结合CiteSpace知识图谱分析软件，从发文数量分布特征、合作网络、关键词共现、突现词分析、共被引聚类等角度对以绿肥施用为研究主题的知识图谱进行了分析。【结果】①该研究领域的论文数量与被引用迅速增加，目前正处于快速发展阶段；研究学者之间形成了较为局限的合作圈。②目前该领域研究热点聚焦于结合模型模拟与微生物机制解析关注绿肥的协同效应。CH4和N2O减排的研究占比始终超50%，且N2O减排的研究近期显著增加，占比超70%。在稻田中温室气体减排和作物产量等效应的研究始终超过50%，是绿肥施用的首要研究场地。③该领域演变呈三阶段特征：初期开展短期实验研究绿肥施用的减排效应，中期逐渐转为减排增产等综合长期效应研究，近期则转向环境与微生物机制及综合效益评估，揭示背后机理。【结论】该领域目前的研究热点主要集中在结合模型模拟与微生物机制解析、长期碳固存以及多措施协同效应；未来需强化多措施协同效益并结合模型模拟验证长期效应，建立经济评估机制促进推广。 |

| Abstract: |
| 【Objective】Excessive chemical fertilizer application in agriculture has resulted in non-point source pollution and increasing soil greenhouse gas emissions, which poses a threat to ecological security and agricultural sustainability. Green manure is an environmentally friendly alternative and plays a vital role in mitigating these issues. This paper analyses the research progress and development trends of green manure application in reducing farmland greenhouse gas emissions.【Method】Based on the Web of Science Core Collection database, bibliometric methods combined with statistical software (Origin) and knowledge mapping tools (CiteSpace) was used in this paper. Using multiple analytical perspectives, including publications, researcher collaborative networks, keyword co-occurrence, emergent term detection and co-citation clustering, we systematically analysed the knowledge landscape of green manure application research related to greenhouse gas emissions.【Result】 ① The number of publications and citations in this field has increased rapidly, indicating that the research is in the stage of rapid development. However, researcher collaboration networks are relatively fragmented and limited. ② Current research focuses on synergistic effects of green manure, primarily conducted through model simulations and microbial mechanism analyses. Studies on reducing CH4 and N2O emission account for more than 50% of the total publications, with N2O-related studies increasing significantly to 70%. Research on effects of green manure on reducing greenhouse gas emission and affecting crop yield in paddy fields accounts for more than 50% of the publications, making paddy fields the primary research area for green manure application. ③ Research history of this field can be divided into three distinct stages: initial stage that focused on short-term experimental studies of effects of green manure on reducing soil greenhouse gas emission; middle phase that the focus to long-term effects of green manure application in synergistically reducing soil greenhouse gas emission and increasing crop yields; and latest stage that focuses on in-depth understanding of environmental and microbial mechanisms of green manure application, as well as its benefit assessment.【Conclusion】Current research priorities in green manure applications include model simulations and microbial mechanism analysis, its efficacy in long-term carbon sequestration, and its synergistic effects with other cultivation measures. Future research should focus on assessing its environmental, economic and agronomic benefits, evaluating its long-term effects, improving model accuracy and reliability, and establishing a scientific economic evaluation system to facilitate rational application of green manure. |
