1992—2020年我国湿地生态系统研究热点可视化分析

Visual analysis of research hot-spots for wetland ecosystems in China from 1992 to 2020

湿地生态系统在维护生物多样性、促进生态环境可持续发展等方面具有重要的作用.以“湿地生态系统”为主题的文献为数据源,借助计量学软件Citespace分别从发文量、作者分布、研究机构、关键词共现、关键词聚类、突变关键词等方面对我国1992—2020年湿地生态系统的相关研究进行知识图谱可视化分析.结果显示:(1)我国湿地生态系统的研究在中文核心期刊发文量总体经历了“缓慢增加—快速增长—稳定波动”的发展历程;(2)生态系统服务价值、生态系统服务功能、可持续发展等是湿地生态系统研究领域的热点内容;(3)我国湿地生态系统的研究视角多元化、方法多样化,但我国湿地生态系统健康评价等方法体系亟待完善.

Wetland ecosystem plays an important role in maintaining biodiversity and promoting the sustainable development of ecological environment.Taking“wetland ecosystem”as the theme of the literature as the data source,with the help of metrology software Citespace,this paper analyzes the related research of wetland ecosystem in China from 1992 to 2020 from the aspects of publication,author distribution,research institutions,keyword co-occurrence,keyword clustering and mutation keywords.The results show that:(1)The research on wetland ecosystem in China has experienced the development process of“slow increase-rap idgrowth-stable fluctuation”in Chinese core journals;(2)Ecosystem service value,ecosystem service function and sustainable development are hot topics in the field of wetland ecosystem research;(3)The research perspectives and methods of wetland ecosystem in China are diversified,but the method system of wetland ecosystem health evaluation in China needs to be improved.
