Research Context and Trend of Domestic Agricultural Biochar:Visual Analysis Based on CiteSpace

【目的】农业用生物炭是提高作物产量、实现农业可持续发展的重要举措.通过对我国农业用生物炭研究脉络和趋势探讨的分析,为其发展和未来研究趋势提供理论指导.【方法】文章使用CiteSpace对与“农业用生物炭”相关的870篇文献进行知识图谱的绘制及可视化分析.【结果】我国农业用生物炭研究领域的发展主要经历了萌芽起步、加速上升、缓慢下降3个主要阶段;该领域的研究员代表主要是潘根兴、李恋卿等;该领域具有代表性的研究机构为南京农业大学和沈阳农业大学;国家层面设立了“国家自然科学基金”“国家重点研发计划”等国家重点基金提供支持;未来我国农业用生物炭的研究趋势可能主要集中在农作物品质改善及增产、农田土壤理化性质的改良及养分的提高、农业生态环境的修复及可持续发展3个方面.【结论】根据文章研究结果,可以客观、科学的看出我国生物炭在农业中应用的相关文献数量及年度变化趋势、高频关键词、高产发文作者、发文机构、主要基金支持及研究前沿,奠定了以农业用生物炭为基础的研究脉络;同时,也为从事相关领域的学者在未来进行多元化扩展提供了有利的参考信息.

Objective:Biochar for agriculture is an important initiative to improve crop yield and achieve sustain-able agricultural development. Through the analysis of the research and trends of biochar for agriculture in China,weprovide theoretical guidance for its development and future research trends.[Methods]The article used CiteSpace tomap and visualize 870 papers related to“biochar for agriculture”. Results:the development of biochar for agriculture in China has gone through three major stages:budding,accelerating,and slow decline. At the national level,the Na-tional Natural Science Foundation of China(NSFC)and the National Key Research and Development Program(NPRD)have been established to provide support. The future research trends of biochar for agriculture in China mayfocus on three aspects:improvement of crop quality and yield increase,improvement of physical and chemical proper-ties of agricultural soil and nutrient enhancement,and restoration of agricultural ecological environment and sustain-able development. Conclusion:Based on the results of the article,it can be objectively and scientifically seen that thenumber and annual trend of relevant literature on biochar applications in agriculture in China,high-frequency key-words,high-yield publishing authors,publishing institutions,major fund support and research frontiers,laying downa research vein based on biochar for agriculture;meanwhile,it also provides a favorable reference for scholars en-gaged in related fields to diversify and expand in the future Information.
