水文水资源学家陈守煜先生学术研究的知识图谱分析

为探索水文水资源学家陈守煜先生学术研究历程及其演变规律,以其335篇文献作为数据基础,采用共现分析等文献计量可视化分析方法,通过文献发表的时间分布、学科和期刊分布、高被引文献分布和研究主题等方面的知识图谱分析,系统分析了陈先生的学术研究历程。结果显示:陈守煜先生学术研究生命周期历时达62年,在其60岁后出现了2个学术创新高峰期;其学术研究特色荟萃于其河渠非恒定流计算、模糊集理论的水文水资源应用、模糊水文水资源学基本理论、模糊聚类-识别-优选统一理论、可变模糊集理论和可变模糊集理论的水文水资源应用6个研究主题,其中主题1为后续的5个模糊水文水资源学创新主题奠定了数值计算的研究方法论,主题2为模糊集现有理论的应用探索,主题3至主题5为面向工程应用的模糊集理论不断深入创新,主题6为可变模糊集理论的应用探索,形成了"紧密结合应用-持续理论创新-创新理论再应用"这种理论与实践互馈的研究特色。他每一阶段的研究目标比较集中、明确,与其研究主题密切对应,显著提高了研究效率;他的学术研究影响广泛,合计被引8554次,缘于他的源头理论创新。陈先生的研究,理论与应用不断互馈,贵在厚积薄发、深入钻研、持续创新,其研究理念和方法论,对水利科学的学术创新研究具有重要的启示作用和深远影响。

Knowledge map analysis of academic research of Mr. Chen Shouyu, hydrological and water resources specialist

In order to explore the academic research process and its evolution characteristics and research rules of Mr. Chen Shouyu, a hydrological and water resources specialist, based on the data of 335 documents writing by Mr. Chen Shouyu collected by CNKI database,using the methods of bibliometric visualization,such as co-occurrence analysis,through the knowledge atlas analysis of the time distribution of documents published, the distribution of disciplines and periodicals, the distribution of highly cited documents, and research topics and other aspects, systematically analyzed Mr. Chen Shouyu''s research process. The results show that:1) In the life cycle of academic research, his academic innovation research lasted 62 years,and two peaks of academic innovation appeared after the age of 60. 2) In the characteristics of academic research, his academic achievements gathered six research themes:"calculation of unsteady flow in river channels", "application of fuzzy set theory in hydrology and water resources", "basic theory of fuzzy hydrology and water resources science", "unified theory of fuzzy clustering-recognition-optimum selection", "variable fuzzy set theory","application of variable fuzzy set theory in hydrology and water resources", theme 1 lays a methodological foundation for the following five innovative topics of fuzzy hydrology and water resources science, theme 2 is the application exploration of the existing theory of fuzzy sets, theme 3 to 5 is the engineering application-oriented theory of fuzzy set, theme 6 is the application and exploration of the new theory of variable fuzzy set,it has formed the research feature of mutual feedback between theory and practice, that is "close combination of application-continuous theoretical innovation-re-application of innovation theory". Where the research objectives of each stage are relatively concentrated and clear, and closely correspond to his research theme, which significantly improves the efficiency of research. 3) In the impact of academic research,his academic research aims at theoretical innovation at the source,so his academic impact is extensive,his publications were cited 8554 times. In Mr. Chen''s research,theory and application feed each other continuously,which is due to the accumulation,in-depth study and continuous innovation. His research philosophy and methodology play and important enlightening role and far-reaching influence on the academic innovation research for water science.
