基于CiteSpace的道路对野生动物的影响研究进展分析

Research progress analysis for the impact of roads on wildlife based on CiteSpace

  • 摘要:
    目的 综合评估道路生态学领域国际合作现状、研究趋势以及国内外研究的差异。
    方法 通过CiteSpace的关键词聚类、关键词时区图(Timezone)、关键词凸显几种可视化分析方法对道路生态学相关文献进行分析。
    结果 统计结果表明,WOS被引量前5文献总被引频次(823)要远高于CNKI(250)。在道路对野生动物不利影响的研究方向,已从对单一物种、单一道路的研究过渡到对道路网络、混合物种的研究,阻碍效应(disturbance)是近几年的热点研究关键词;在缓解措施的研究方向,最初几年并未受到广泛关注,直到2016年该方向才大批量出现关键词,随着研究深入,该方向的研究也从地下通道(underpasses)转移到了对涵洞(culvert)上。在国际合作方面,尽管中国取得了进展(合作强度系数C=0.03),但与美国(C=0.46)、英国(C=0.22)、挪威(C=0.17)等国家相比,合作强度仍有显著差距。在国内外研究对比中,国内研究更侧重于野生动物通道的有效性评价和措施应用,而国外研究则更注重于道路影响的根源探究。在野生动物监测技术方面,国内的发展相对滞后,亟须与国际先进水平接轨。
    结论 强调了加强国际合作、关注研究热点以及提升监测技术的重要性,为未来道路建设与野生动物保护的研究提供了新的视角和建议。

     

    Abstract:
    Objectives To comprehensively evaluate the current status of international cooperation, research trends, and differences between domestic and international studies in the field of road ecology.
    Methods This paper analyzed relevant literatures on road ecology using several visualization analysis methods, including keyword clustering, keyword timezone, and keyword burst in CiteSpace.
    Results The results indicated that the total citation frequency of the five most frequently cited articles in the Web of Science (WOS) database (823) was much higher than that in the China National Knowledge Infrastructure (CNKI) database (250). The research on the adverse effects of roads on wildlife has shifted from studies on single species and single roads to studies on road networks and mixed species. The term “disturbance” has emerged as a prominent research keyword in recent years. However, this direction did not receive widespread attention in the early years of research on mitigation measures. It was not until 2016 that a significant number of keywords appeared. With the deepening of research, the focus of this direction has also shifted from “underpasses” to “culverts.” In terms of international cooperation, although China has made progress in international cooperation (cooperation intensity coefficient C=0.03), compared with the United States (C=0.46), the United Kingdom (C=0.22), Norway (C=0.17), and other countries, there was still a significant gap in cooperation intensity. A comparison of domestic and international studies revealed that domestic research tended to prioritize the evaluation of the effectiveness of measures for wildlife passages, wheras foreign research was more inclined to examine the underlying causes of road impacts. With regard to wildlife monitoring technology, the development in China was relatively lagging behind and required urgent catch-up with the international advanced level.
    Conclusions The conclusions of this study underscored the importance of strengthening international cooperation, focusing on research hotspots, and improving monitoring technology, providing new perspectives and suggestions for future road construction and wildlife protection research.
