基于文献计量和知识图谱的湿地生态价值评估研究进展

Research Progress of Valuation on Wetlands: A Review Based on Bibliometrics Method and Knowledge Graph

自20世纪70年代以来,湿地生态价值评估领域取得了大量研究成果。对已有工作进行总结,有利于把握学科发展趋势,明确后续研究方向。应用文献计量与文献综述相结合的方法,梳理了1975年以来国内外湿地生态价值评估的相关文献,对该领域研究从总体趋势、主要研究力量、学科演变过程、研究热点等方面进行了分析,对比和总结了国内外研究进展及特点,并结合知识图谱对分析结果进行直观展示。在此基础上提出未来我国湿地生态价值评估研究的关注重点:(1)加强国际合作;(2)提高经济模型的应用能力;(3)加强生态学方法与经济学方法的融合;(4)提高价值评估结果对相关决策的针对性。

Since the 1970s,a great number of research achievements have been obtained in the field of wetland ecological valuation.A comprehensive review on the research progress has a great significance for understanding the development trend of the subject and identifying the follow-up research direction.With the help of bibliometric method,by sorting out the relevant literatures on ecological valuation on wetlands at home and abroad since 1975,this paper analyzes the general trends,main research strength,evolution process of subjects and the research hotspots in this field.Moreover,we compare the progress and characteristics of research works between China and abroad and display the results by the knowledge map.Based on the these analysis and discussion,this paper suggests that in future researches,China should focus more on(1)strengthening international cooperation,(2)improving the application capacity of economic models,(3)strengthening the integration of ecological methods and economic methods,and(4)making studies more problem-oriented to facilitate the mainstreaming of valuation results on relevant decision making.
