基于CiteSpace的农业节水研究进展与发展趋势

Research progress and development trend of water saving agriculture based on Cite Space

借助Cite Space可视化软件,对无形的科学知识进行了可视化计量研究。利用共引共词分析、多元统计分析、社会网络分析等方法,绘制了农业节水研究领域的科技文献共引网络图谱、高被引文献的热点词图谱以及前沿进展时区图谱。分析可知国内外有关农业节水的高被引文献多数是关于实验方法和技术应用,目前国内比较侧重于节水灌溉、水资源、节水型社会、农业节水技术方面的研究;国外有关农业节水研究热点主要集中在灌溉水利用效率、灌溉水资源、虚拟水、农业产量及种植结构等。国内在基于作物水分高效利用的遗传育种学及分子生物学方面研究相对薄弱,作物抗旱及水分高效利用机理、水分养分耦合及高产协调机理等生物节水方面有待进一步研究;在多种农业节水技术联合运用方面研究有待加强;农业节水的生态环境效应评价方面研究是未来农业节水研究的发展趋势。

By use of the critical documents and frontier knowledge, the paper used CiteSpace information visualization software to carry out visualization qualitative research for invisible scientific knowledge.Using cocitation analysis, multiple statistical analysis and social network analysis,it drawn the citation network map, the highly cited references map and the advanced progress hot word time zone map in water saving agriculture research.The results show that most of the literature of agricultural water saving at home and abroad highly cited are about the experimental method and the technology application.In recent years, China more focuses on the research of water-saving irrigation, water resources, water-saving society, agri-cultural water saving technology.The relevant agricultural water-saving in foreign country early focuses on intense research in irrigation water use efficiency and irrigation water resources, virtual water, agricultur-al production and planting structure.The domestic research on the efficient use of crop water-based genet-ic breeding and molecular biology is relatively weak.The biological water-saving mechanism of crop resist-ance to drought and high water use efficiency, water nutrient coupling and high yield coordination mecha-nism need to study further.The joint utilization of agricultual water saving technology needs to be strength-ened;the effects evaluation of agricultural water-saving agricultural water-saving on eco-environmental is the research trends in the future.the analysis tools of mapping knowledge domains based on CiteSpace vi-sualization, which make up for the subjectivity shortcoming of scientists traditional methods, and has im-portant academic reference value for the exploration and discovery of the evolution law of disciplines hotspots and the latest development trend.
