摘要
目的直观把握PHA相关领域的研究进展和热点,推动PHA领域的发展。方法以CNKI与Web of Science数据库中近10年的相关文献为对象,采用文献计量方法,使用CiteSpace软件绘制PHA研究知识图谱。结果相关文献的年度发文量不断上升,国内外学术界对PHA领域的关注度越来越高,国际PHA领域的跨单位合作比国内更广泛。该领域的研究力量遍布全球,其中清华大学、葡萄牙里斯本新大学、马来西亚理科大学、昆士兰大学、布尔诺理工大学等机构的贡献突出、影响较大,陈国强是该领域发文量最多的学者。通过分析关键词可知,目前对PHA的关注重点主要集中在力学性能、生物降解、混合菌群、活性污泥、除磷脱氮等方面。结论在未来的PHA研究中,PHA的增强改性、在活性污泥中提取PHA及生物法合成PHA仍是研究热点。
The work aims to intuitively master the research progress and hot spots in PHA-related fields and promote the development of PHA field.With the related literature in CNKI and Web of Science in the past ten years as the objects,the knowledge map of PHA research was drawn by the CiteSpace software with the bibliometric method.The annual number of publications of related literature increases continuously,the academic communities in China and abroad are paying more and more attention to the PHA field,and the cross-unit cooperation in the international PHA field is more extensive than that in China.The research power in this field is spread all over the world,among which Tsinghua University,NOVA Univ Lisbon,University of Science Malaysia,University of Queensland,and Brno University of Technology are prominent in their contribution and influence.CHEN Guoqiang is the scholar with the largest number of publications in this field.Key word analysis shows that the current focus of attention on PHA is mainly concentrated on mechanical properties,biodegradation,mixed flora,activated sludge,phosphorus and nitrogen removal.In the future research,enhanced modification of PHA based on increasing its structural diversity,extraction of PHA in activated sludge and biological phosphorus removal and nitrogen removal,biosynthesis of PHA,and mixed bacterial colony fermentation will be the future research trends in the field of PHA.
