基于文献计量的沼渣沼液处理利用技术研究态势分析

Research Status and Trends of Biogas Residue and Biogas Slurry Treatment and Utilization Based on Bibliometrics

基于文献计量方法对中国知网数据库2010~2019年间沼渣沼液研究领域中文文献进行可视化分析,并对沼渣沼液处理与利用技术研究热点进行分析。结果表明:近十年沼渣沼液领域研究成果显著,研究机构众多,研究范围广,热点领域随研究的深入有所转变,逐渐由传统处理利用技术向多元化、高值化利用技术拓展;应用研究所占比重较大,尤其是肥料化利用方面,在施用品种、施用比例、效果和品质以及环境影响等方面的研究趋于深入。未来沼渣沼液肥料利用的标准化、长效安全评估以及沼渣沼液的高附加值处理技术将是研究的热点方向。

In this paper,a visual analysis on research literature of biogas residue and biogas slurry from 2010 to 2019 in CNKI Chinese database was conducted by bibliometric method.The research hotspots in this area were analyzed.The results indicated that there was remarkable achievements in recent ten years,numerous research institutions were involved and the research scope was wide,with the deepening of the research,the hotspot areas had gradually changed from traditional treatment and utilization technology to diversified and high-value utilization technology,especially in the aspect of fertilizer utilization.The research tended to deepen in the aspects of applicable crops,application proportion,effect and quality,and environmental impact.The standardization of biogas residue and biogas slurry utilization,long-term safety assessment and high value-added treatment will be the hot research directions in future.
