基于CiteSpace的景观连通性研究文献计量分析

Bibliometric Analysis of Landscape Connectivity Research Based on CiteSpace

随着气候变化和人类活动对景观格局及生态过程扰动的增强,关于景观连通性的研究越来越多,但缺乏系统的文献梳理,对其研究现状及前沿热点认识不足。基于Web of Science核心合集数据库检索的文献数据及文献计量学软件CiteSpace,对2000—2021年景观连通性研究的发文数量、发文学科、研究力量以及高被引文献等进行可视化分析。结果表明:(1)近20年来,该研究历经了缓慢发展、稳步增长和快速发展阶段,主要分布于生态学、环境科学和地理科学等学科。(2)中国科学院和北京师范大学发表了较多相关成果,大大提升了中国在此研究领域中的国际影响力。(3)景观连通性相关研究的基础内容主要包括探究生物物种扩散机制、自然保护区设计构建与生态网络规划、景观破碎化分析等。发展与应用景观连通性相关评估指标与模型是主要热点内容,从连通性角度开展泥沙输移过程的量化、生物多样性保护与生态系统服务功能评价、气候变化与人类活动双重影响下水文连通性多尺度效应评估是研究前沿。

As the intensified climate change and rising stress from human activities on landscape patterns and landscape ecological processes,landscape connectivity research receives more and more attention worldwide.However,the relative research status and hotspots are still lack of systematic analysis.In this study,the number of papers,subject,study strength,and highly cited literature about landscape connectivity research from 2000 to 2021 were analyzed based on the Web of Science core collection database retrieval and the bibliometric software CiteSpace.The results showed that:(1)in the past 20 years,the research about landscape connectivity experienced the stages of slow development,steady growth and rapid development,and it was mainly distributed in ecology,environmental science and geographical science.(2)The Chinese Academy of Sciences and the Beijing Normal University published many achievements in relative journals,greatly enhancing China’s international influence in this research field.(3)There was some basic research on landscape connectivity,including the exploration of species diffusion mechanism,the design and planning of nature reserves and ecological network,the analysis of landscape fragmentation,etc.The hotspots were mainly focused on developing and applying the related indicators and models of landscape connectivity.The current research frontiers include the quantification of sediment transport process from the perspective of connectivity,biodiversity conservation and assessment of ecosystem services,and the evaluation about the multi-scale effects of hydrological connectivity under the combined influence of climate change and human activities.
