| 摘要: |
| 【目的】为了探明国内外暗管排水研究领域的研究内容、发展动态,【方法】基于CNKI与WOS数据库,采用科技文本挖掘可视化软件VOSviwer对国内外暗管排水研究的文献引文数据进行了科学叠加可视化分析,国外机构耦合分析,国内外引文关键词共现分析,国内外研究人员合作网络分析。【结果】通过科学叠加图谱,从学科的宏观角度分析了暗管排水研究学科发展方向；通过机构耦合分析,指出暗管排水研究高影响力研究机构；通过国内外关键词共现网络图比较,揭示了国内外暗管排水研究的主要内容上的差距；通过国内外合作网络图分析,指出了国内外暗管排水核心研究学者之间的合作关系及他们为推动暗管排水研究所做的贡献。【结论】研究指出我国的暗管排水研究领域正处于引进吸收与发展的状态,在流域尺度暗管排水的研究、田间尺度农药与磷淋失机制、排水水质净化研究薄弱。未来的新兴趋势是从暗管排水景观的源头到排水的末端建立系统的研究体系,考虑多元化因素的排水管理,工程技术上在田间排水源头采用建立反硝化除氮生物反应池改善排水水质,农艺措施上非耕作期进行覆盖作物种植研究,气候变化与暗管排水研究耦合也将成为研究热点。 |

| Abstract: 【Objective】To explore the content and emerging trends of subsurface drainage research at home and aboard【Method】Analyzing literature citation data of subsurface drainage research download from WOS and CNKI database, by adopting scientific text mining visualization software VOSviewer, and through science overlay map analysis, institute bibliographic coupling analysis, keywords co-occurrence analysis and author co-authorship network analysis.【Result】Through the scientific overlay map, the development direction of the subsurface drainage research discipline is analyzed from the macroscopic point of view; through the country cooperation analysis, the research power was pointed out; through the institute bibliographic coupling analysis, the high-impact research institution of the subsurface drainage research is pointed out; through the comparison of the domestic and international keyword co-occurrence network map, the domestic The gap between the main contents of the subsurface drainage research; through the analysis of the cooperation network map domestic and international, pointed out the cooperation between the scholars at home and abroad, and their contribution to the study of the subsurface drainage research discipline【Conclusion】The research indicates that the research field of subsurface drainage in China is in the state of introduction and absorption. The research of subsurface drainage in the basin scale, the mechanism of pesticide and phosphorus leaching in the field scale, and the purification of drainage water are weak. The emerging trend in the future is to establish a systematic research system from the source of the subsurface drainage landscape to the end of the drainage, considering the diversified factors of drainage management, and engineering to improve the drainage water quality by establishing a denitrifying nitrogen removal biological reaction tank at the source of the field drainage. The agronomic measures on the non-cultivation period cover crop planting research, and the coupling of climate change and subsurface drainage research will also become a research hotspot. |
