基于文献计量分析的生态系统恢复力研究进展

该文基于VOSviewer和Histcite文献计量方法,以CNKI数据库和Web of science核心合集中生态系统恢复力研究文献为对象,通过对文献数量、高频关键词的分析,总结国内外恢复力研究的脉络和内容演变。研究发现:1)生态系统恢复力研究领域发表的文章数量总体上呈上升趋势,文献主要来源于美国;2)国际恢复力研究经历了从基础理论到政策管理及技术应用,各个方向存在相互的引证关系,分析研究热点的时序演化发现,2000年前,以恢复力的内涵和基础理论为研究重点;2001-2010年间,珊瑚礁的测度模型及提升路径成为热点;近10 a来,恢复力研究领域进一步扩大,研究方法更加多样化;3)与其他国家相比,中国的恢复力研究起步较晚,侧重于应用基础研究,集中于恢复力的工程措施、调查监测手段以及影响因素的探讨。

Research progress of ecosystem resilience based on bibliometric investigation

Due to the climate change and human activities, the global ecosystem has changed significantly, which leads to the continuous decline of ecosystem resilience at the regional and even global scale and constrains the sustainable development of ecosystems. The question about how to maintain the sustainable development ability of ecosystem and reduce the influence of uncertainties has attracted extensive attention of scholars at home and abroad. A theory based on ecosystem resilience has provided a framework for solving these problems, but at present, the research of resilience is in the initial stage. Based on this, this paper takes the documents in CNKI database and Web of science database as samples. In CNKI database, the subject is "ecosystem resilience", and in Web of science core database, the topic is "resilience" & "ecological system" or "marine ecological resilience" or "wetland ecological resilience" or "forest ecological resilience" or "grassland ecological resilience" or "desert ecological resilience" not "social-ecological system" not "urban system" not "community system".The Histcite citation visualization software is used to select 40 papers with the highest local citation score (LCS), generating citation chronicles of foreign ecosystem resilience literature, with a time span of 1990-2019, so as to analyze the development of resilience research in foreign countries. In the analysis of domestic research hotspot trends, it is mainly to analyze the quantity of keywords appearing at different stages, and to study the evolution of resilience content. At the same time, this paper also uses VOSviewer data processing software to perform co-occurrence and cluster analysis on keywords, and generates a network map of keywords co-occurrence relationship to understand the main research direction of ecosystem resilience at home and abroad.The findings are as follows: 1) On the whole, the research on ecosystem resilience at home and abroad is on the rise in quantity, and the documents are mainly from the United States. The journals published in the field of ecosystem resilience research at home and abroad tend to focus on ecology and resources. Research institutions include comprehensive colleges, and the universities of mining, teacher education, academy of sciences, and some administrative institutions. 2) At the international level, the focus is different at different stages. Judging from the emergent words, the early stage focuses on biodiversity protection and ecosystem stability. After 2010, more attention is paid to the research of practical policies on the resilience of specific ecosystems. According to the results of citation analysis, resilience is researched from theoretical discussion to specific case modeling, and the research object extends from marine ecosystem to forest ecosystem. The results of co-occurrence analysis and cluster analysis of key words show that the research topics of international resilience focus on biodiversity, basic theory, policy management and the stability of marine ecosystem (especially coral reef). 3) Compared with other countries, China''s resilience research starts late, and the research direction of ecosystem resilience in China mainly includes three aspects: land reclamation, land investigation and monitoring means, and research on influencing factors. In recent years, social ecosystem resilience, and sustainability and stability of ecosystem have become research hotspots.
