基于CNKI的中国秸秆还田研究态势分析

Research Situation Analysis of Straw Returning in China Based on CNKI

为准确客观地分析我国秸秆还田领域的发展趋势,同时为秸秆资源高效利用提供参考,利用CNKI全文数据库,分析了该领域相关论文的出版时间、论文数量、研究机构、被引用量等指标,结合CiteSpace关键词可视化分析方法,系统阐述了我国秸秆还田领域的研究概况,分析了我国秸秆还田研究的热点及发展趋势。结果表明:我国秸秆还田研究正处在快速发展阶段,论文的发表量呈指数增长;发文量排名前三的研究机构依次是中国农业大学、西北农林科技大学和南京农业大学,在该领域的活跃研究者有来自华中农业大学的鲁剑巍、甘肃农业大学的张仁陟和中国农业大学的陈阜;发表的相关文章分布在《农业工程学报》《植物营养与肥料学报》《土壤通报》等期刊;我国秸秆还田研究的热点主要集中在耕作农艺措施调控以及采取秸秆还田措施的效应研究,主要包括增加产量、提高土壤肥力以及相关生物学机制研究等方向。总体而言,我国秸秆还田的研究热点从产量、土壤肥力变化研究向秸秆还田的生物学机制研究转变。土壤温室气体排放、土壤微生物和土壤酶反应是我国未来秸秆还田研究的主要趋势。

In order to accurately and objectively analyze the development trend of straw returning field in China,and provide a reference for the efficient utilization of straw resources,CNKI full-text database was used to analyze the publication time,number of papers,research institutions,citation and other indicators of relevant papers in this field.Combined with the CiteSpace keyword visual analysis method,the research overview of straw returning field in China was systematically described,and the hot spots and development trends of straw returning research in China were analyzed.The results showed that the research on straw returning to the field in China was in the stage of rapid development,and the number of papers published increased exponentially;The top three research institutions in the volume of papers were China Agricultural University,Northwest Agriculture and Forestry University and Nanjing Agricultural University.Lu Jianwei from central China Agricultural University,Zhang Renzhi from Gansu Agricultural University and Chen Fu from China Agricultural University were active researchers in this field;Relevant articles published were distributed in journals such as Transactions of the Chinese Society of Agricultural Engineering,Journal of Plant Nutrition and Fertilizer Science,and Chinese Journal of Soil Science;The hotspot of straw returning research in China mainly focused on the regulation of farming and agronomic measures and the effect of straw returning measures,mainly including increasing yield,improving soil fertility and related biological mechanisms.In general,the research focus of straw returning in China has changed from the yield and soil fertility to the biological mechanism of straw returning.Soil greenhouse gas emissions,soil microorganisms and soil enzyme reactions were the main trends of straw returning research in China in the future.
