摘要:

了解秸秆综合利用领域研究应用的热点和前沿,有助于制定并优化秸秆资源化的政策。文章以CSCD和SCI-E数据库为获取秸秆综合利用研究领域中英文文献的数据来源,比较分析1999—2003、2004—2008、2009—2013和2014—2019年4个时间段肥料化、燃料化、饲料化、原料化和基料化等5个应用方向的中英文文献的分布比例及发表论文的高频关键词,确定秸秆综合利用的研究热点与前沿。结果表明,近20年,国内外学者和机构为推动秸秆综合利用研究,做出了巨大贡献,发文量呈现不断增长的趋势。肥料化始终是秸秆综合利用领域中文文献最主要的研究方向,英文文献中肥料化和饲料化应用方向的发文量占比不断下降,而燃料化的发文量占比不断上升;原料化和基料化应用研究在中英文文献中始终关注度较低。2009年前,中文文献比较关注秸秆还田对土壤改良和培肥的影响,而英文文献的关注点聚焦于饲料化的可消化性和对牲畜生长性能等影响,以及对作物产量、土壤有机碳等影响的肥料化应用上;2009年后,中文文献更多研究保护性耕作和作物产量变化以及土壤微生物群落结构等,而英文文献转向制备生物乙醇、沼气、秸秆生物质热解等燃料化应用和土壤微生物、土壤养分管理等肥料化应用上。近年来,中文文献研究前沿主要集中于秸秆还田对土壤和作物的影响、秸秆热解和发酵以及秸秆复合材料应用等;而英文文献研究秸秆综合利用对环境(如土壤碳环境和温室气体排放等)的影响、秸秆生物质热解燃烧、秸秆发酵制备生物乙醇和沼气、还田对土壤微生物及氮磷养分等影响,点多面广。高频关键词聚类分析,对大数据进行可视化展示,可反映近20年秸秆综合利用的研发历程,为下一步更好发挥秸秆的耕地保育、种养循环、节能减排等功能提供借鉴意义。

Abstract:

Understanding the hotspots and frontiers of research and application in the field of straw comprehensive utilization will help to develop and optimize the governmental policies for straw utilization. In the present paper, we use the CSCD and SCI-E databases as the data sources to obtain the Chinese and English literature in the field of straw comprehensive utilization research. Comparative analysis of the distribution ratio of Chinese and English literature and high-frequency keywords of published papers in the five application directions of fertilization, fuel, feed, raw material and base material in the four time periods of 1999-2003, 2004-2008, 2009-2013 and 2014-2019 to determine the research hotspots and frontiers of straw comprehensive utilization. The results showed that in the past 20 years, domestic and foreign scholars, and institutions have made great contributions to promote straw comprehensive utilization research, and the number of publications has shown an increasing tendency. In Chinese literature, application as fertilizer has always been the most important research direction. The number of articles on fertilization and feed applications in the English literature has been decreasing, while the number of articles on fuel has been increasing. Raw materials and culture media application studies have always received less attention in the Chinese and English literature. Before 2009, the Chinese literature was more concerned with the effects of straw return on soil improvement and fertilization, while the English literature focused on the fodder digestibility and its effects on the growth performance of livestock, and the applications on crop yield, soil organic carbon as a fertilizer. After 2009, the Chinese literature focused more on the effects of straw fertilizer on conservation tillage, crop yield changes and microbial community structure in soils, while the English literature shifted to develop straws as fuels (such as the production of bioethanol, biogas and pyrolysis of straw biomass) and investigate the effects of fertilizers made from straws on soil microbiology and nutrients management. In recent years, the research frontiers in Chinese literature mainly focus on the effects of straw returning on soil quality and crop growth, the pyrolysis and fermentation of straws, and the straw composite material applications. While English literature studies, the effects of straw comprehensive utilization on the environment (such as soil carbon cycle and greenhouse gas emission, etc.), the pyrolysis and combustion of straw biomass, the fermentation of straws to produce bioethanol and biogas, and the effects of returning straw on soil microorganisms and nitrogen and phosphorus nutrients in a wide range of points. Cluster analysis of high-frequency keywords visually displayed the big data of the research and development history of straw comprehensive utilization in the past 20 years, and provide reference meaning for the next step to better play the functions of straw as arable land conservation, breeding cycle, energy saving and emission reduction.
