国内生态效率研究知识图谱分析——基于CNKI数据

Analysis of Knowledge Map of Domestic Ecological Efficiency Research:Based on CNKI Data

把握生态效率研究发展的脉络与趋势,对优化国土空间开发保护格局、践行绿色发展理念和推动生态文明建设具有重要意义。文中利用CiteSpace知识图谱分析工具对中国知网(CNKI)中检索到的生态效率相关文献进行可视化分析,揭示了国内生态效率研究的现状、热点和发展趋势。研究发现:(1)我国生态效率研究主要始于1992年,此后呈现逐年上升的趋势,尤其是在2013年之后呈现快速增长的态势。(2)生态效率研究作者和机构过于分散,集中度较低,没有形成合作体系。(3)生态效率的研究主题主要集中在研究方法、区域生态效率、产业生态效率、生态和经济的关系四个方面。(4)生态效率的研究方法逐渐向空间计量方向转变,研究尺度逐渐细化,研究领域和重点与国家经济发展趋势相匹配,有明显的政策引导效应。(5)区域生态效率和产业生态效率是当前生态效率研究的前沿主题。

Grasping the context and trends of the development of ecological efficiency research is of great significance in optimizing the development and protection pattern of land space,practicing the concept of green development,and promoting the construction of ecological civilization.This paper uses the CiteSpace knowledge graph analysis tool to visually analyze the ecological efficiency related literature retrieved from the CNKI,revealing the current status,hotspots and development trends of eco efficiency research.The research found that:(1)The research of ecological efficiency in China began in 1992,and then showed an increasing trend year by year,especially after 2013.(2)The authors and institutions of eco efficiency research are too scattered,with low concentration,and no cooperative system is formed.(3)The research topics mainly focus on research methods,regional eco efficiency,industrial eco efficiency and the relationship between ecology and economy.(4)The research methods of eco efficiency are gradually shifting to the direction of spatial measurement,the research scale is gradually refined.And the research fields and priorities match the national economic development trend,which has obvious policy guidance effect.(5)Regional ecological efficiency and industrial ecological efficiency are the frontier topics of current ecological efficiency research.
