- 摘要:
- 为全面把握我国中低产田改良领域的发展现状和动态，从而促进中低产田土壤改良和耕地保育，以中国 CNKI 数据库中检索到的中低产田文献为研究对象，运用文献计量学方法收集和分析该领域文献的发文量、涉及学科、文章发表情况、文献来源、所属机构和关键词情况，对我国中低产田研究的现状和发展趋势进行了综述，揭示了该领域关注焦点和研究热点。结果表明，我国中低产田改良领域的研究起步于20世纪80年代，截止2024年总计发表920篇学术文章和15篇学位论文；不同年份发表的学术文章数量从整体上看呈起伏状，3个峰值的阶段分别为1991-1992年、1995-1997年及2012-2014年；学术文章涉及的前6个学科分别为农业基础科学、农艺学、农业经济、农作物、自然地理学和测绘学以及农业工程；研究开始较早的是辽宁、广西以及北京等的研究机构，发表文章排在前三的省份分别是新疆、江苏、辽宁和河北。整体文献中核心期刊比例不高，需加强深入研究。通过关键词聚类分析和共现分析，该领域研究主要集中在分类、改良措施、评价以及作物产量等方面。中低产田改良培肥与国家粮食安全密切相关，分析其成因、种类划分、评价方法以及改良利用等诸多方面，农艺与工程相结合是我国中低产田改良的重要途径，集成、配套其他相关技术，最终实现土壤障碍因素消减、土壤肥力提高以及耕地综合生产能力提升。
- Abstract:
- In order to comprehensively grasp the research trend and hot issues of improvement of medium-low yield farmland and promote soil improvement and farmland conservation in planting land, this study took the literatures on medium-and low-yield fields retrieved from the Chinese CNKI database as the research object, and used bibliometrics to summarize the current situation and development trend of medium-and low-yield research by collecting and analyzing the publication volume, disciplines involved, and publication status of literature, journal sources, research institutions and keywords. The results showed that the research on improving of medium-and low-yield fields started in the 1980s in China, and a total of 920 academic articles and 15 dissertations have been published until 2024. The number of academic articles published in different years showed an fluctuation pattern, with the three peak years being 1991-1992, 1995-1997, and 2012-2014, respectively. The first six disciplines covers in academic articles were: agricultural basic science, agronomy, agricultural economics, crops, physical geography and surveying, and agricultural engineering. Provinces, municipalities, and research institutions where research began earlier included Liaoning, Guangxi, Beijing, and others, the top three provinces for publishing articles were Xinjiang, Jiangsu, Liaoning, and Hebei. The proportion of core journals in the overall literature was not high, and in-depth research needed to be strengthened. Research mainly focusd on classification, improvement measures, evaluation, and crop yield, etc in this field through class analysis and co-occurrence analysis. The improvement of medium-and low-yield fields were closely related to national food security, analyze its causes, types, evaluation methods, improvement and utilization in many aspects, the combination of agronomy and engineering is an important way to improve and fertilize medium-and low-yield fields in China, at the same time, other related technologies are integrated and matched to ultimately reduce soil barriers, improve soil fertility, and enhance the comprehensive production capacity of cultivated land.
