国际天然林资源保护工程研究的知识图谱分析

Knowledge Mapping Analysis of Research on International NFPP

以Web of Science数据库核心合集1986—2014年的127篇天然林保护工程文献为研究对象,以Cite Space可视化软件为分析手段,尝试从定性判断到定量分析、从图表统计到信息可视化,对国际天然林保护工程研究领域的知识结构、发展脉络、研究机构和研究热点进行深入挖掘,是对天然林保护工程领域文献研究的新尝试。研究结果显示,国际天然林资源保护工程研究基础相对集中,可分为四大聚类,分别是中国天然林保护实践、生态工程经验总结和未来工作重点、发展中国家生态保护、天然林保护与生物多样性研究;从聚类研究脉络看,中国天然林保护实践在国际天然林保护工程研究领域最为突出,其次是发展中国家生态保护和生物多样性研究,生态工程经验总结这类研究近期基本处于沉寂状态;美国、中国、加拿大是国际天然林保护工程领域研究的主要国家,其中美国的研究实力最强,其次是中国;国际天然林保护工程研究热点随着时间的变迁而不断发生变化,近期研究热点指向高频关键词"气候变化"、"碳汇"、"遥感"和"生态旅游"。

This paper takes the 127 natural forest protection project （NFPP） literature from 1986 to 2014 in the core col- lection of Web of Science database as research objects and CiteSpace visualization software as a tool to try an in - depth study of NFPP＇ s knowledge structure, development process, research institutes, and research focus from qualitative judg- ment to quantitative analysis and from graphic statistics to information visualization. It is a new attempt of literature research in the field of NFPP. The results show that the research basis on international NFPP is relatively concentrating on four major clusters including Chinese natural forest protection practice, experience summary and future focus of ecological engineering, ecological protection in developing countries, and research on natural forest protection and biodiversity; from the perspec- tive of cluster research frame, Chinese natural forest protection practice is the most prominent in the field of international NFPP followed by research on ecological protection in developing countries and research on biodiversity while recently re- search on experience summary of ecological engineering has basically no news ; the United States, China, and Canada are major countries studying international NFPP with the US having the strongest research strength and China having the sec- ond ; and the research focuses of international NFPP change as time passes by with the recent high - frequency keywords in- cluding ＂climate change＂, ＂carbon sink＂, ＂remote control＂, and ＂ecological tourism＂.
