摘要: 以中国知网收录的3 233篇盐碱地期刊文献为数据依据,分析了国内盐碱地治理的研究现状。采用文献计量、合作率与合作度、共现分析、聚类分析等研究方法,并通过数据图表和可视化图谱展示了国内盐碱地研究热点和发展趋势。近10年国内盐碱地领域科研论文产出呈快速上升趋势,核心产出机构集中在农业类科研机构和小部分林业院校,高频关键词除盐碱地外还有滨海盐碱地、土壤改良、产量,研究热点主要集中在水稻种植、棉花种植、造林、绿化等,还有部分集中在滨海盐碱地的改良技术研究。

关键词: 盐碱地, 改良技术, 研究热点, 聚类分析

Abstract: Based on the data of 3 233 journal articles in the saline-alkali land collected by CNKI,this paper analyzes the current scientific research status of saline-alkali land management in domestic.The research hotspots and development trends in the field of saline-alkali land in China are demonstrated by using the methods of bibliometrics,cooperation rate and cooperation degree,co-occurrence analysis and cluster analysis.In the past 10 years,the output of scientific research papers in the field of saline-alkali land in China showed a rapid upward trend.The core output institutions are concentrated in agricultural scientific research institutions and a small number of forestry colleges.In addition to saline-alkali land,the high-frequency keywords include coastal saline-alkali land,soil improvement,and yield.The research hotspots mainly focus on rice,cotton,afforestation,greening and etc.,and some focus on the improvement technology research of coastal saline-alkali land.

Key words: Saline-alkali land, Improvement technology, Research hotspot, Cluster analysis
