基于CiteSpace的水生野生保护动物研究可视化分析

Visual Analysis of Protected Aquatic Wildlife Research Based on CiteSpace

水生野生保护动物是水生生态系统中的重要组成部分。文章利用CiteSpace文献可视化软件分析了Web of Science(WoS)核心数据库和中国知网(CNKI)全文数据库中2001—2020年水生野生保护动物相关的文献,对年度发文量、合作机构、国家合作和关键词聚类进行知识图谱分析。研究发现:近20年共发表外文文献634篇,发文量总体呈上升趋势,中文文献128篇,总体呈水平波动趋势;国外发文量最多的机构是美国鱼类及野生动植物管理局,研究机构间合作较为紧密,国内发文量最多的机构是青海省渔业环境监测站,研究机构间的合作分散;美国发文量占比为58.20%,与其他国家交流最为密切,中国发文量占比仅为3.31%,与国际合作关系不紧密;国外的研究热点主要是种群动态分布、栖息地利用和遗传多样性等,海洋与淡水物种均有研究;国内的研究热点主要是区域性保护措施,主要以淡水水生野生保护动物的研究为主,研究范围存在局限性。综合分析认为,我国应增进国内外研究机构间的交流与合作,重视海洋濒危水生野生动物的保护与研究,加强种群动态评估,开展国内对水生野生保护动物栖息地利用与遗传多样性分析的研究,从而实现水生野生保护动物种群的恢复。

Protected aquatic wildlife is an important part of the aquatic ecosystems.This paper used CiteSpace document visualization software to analyze the literature on protected aquatic wildlife from 2001 to 2020 in the core database of Web of Science(WoS)and the full-text database of China National Knowledge Infrastructure(CNKI).This paper conducted the knowledge map analysis of annual publication volume, cooperative institutions, national cooperation and keyword clustering.The study found that a total of 634 foreign language papers were published in the past 20 years, with an upward trend in the number of publications, and 128 documents in Chinese showed a fluctuation trend;the organization with the largest number of foreign publications was the US Fish & Wildlife Service, with closer cooperation among research institutions, the organization with the largest number of domestic publications was the Qinghai Fishery Environmental Monitoring Station, with scattered cooperation among research institutions;the United States issued 58.20% of the articles, and had the most close communication with other countries, China issued only 3.31% of the articles, with limited international cooperation;foreign research hotspots were mainly population dynamic distribution, habitat use and genetic diversity and both marine and freshwater species had been studied;domestic research hotspots were mainly regional conservation measures, mainly focusing on the study of freshwater protected aquatic wildlife and there were limitations in the scope of the study.The comprehensive analysis suggested that China should enhance the communication and cooperation between domestic and foreign research institutions, attach importance to the conservation and research of marine endangered aquatic wildlife, strengthen the population dynamics assessment, and carry out domestic research on the habitat use and genetic diversity analysis of protected aquatic wildlife, so as to achieve the recovery of protected aquatic wildlife populations.
