基于文献计量的森林水源涵养功能研究热点与趋势分析

Bibliometrics Analysis of the Research Hotspots and Trends of Water Conservation Function of Forests

森林作为陆地生态系统水源涵养的主体,其水源涵养功能及其价值的研究一直是森林生态系统服务功能领域研究的热点问题。为探究森林生态系统水源涵养功能的发展脉络、研究热点和前沿趋势,文章基于中国知网(CNKI)和Web of Science(WOS)核心合集数据库,利用可视化工具CiteSpace和VOSviewer绘制森林生态系统水源涵养功能研究的知识结构图谱,分析该领域论文发表的数量动态、国家与机构合作关系、热点问题及前沿动态等。结果表明:全球范围内,森林生态系统水源涵养领域的发文量稳步上升,尤其是中国在该领域研究的国际影响力逐年提升;从发文量来看我国居第一位,但美国与其他国家间的合作更为密切;该领域的发文机构中,中国科学院在CNKI数据库和WOS数据库收录的文献量均是最多。森林生态系统水源涵养的中、英文文献研究热点分别为森林水源涵养功能、生态系统服务及其对气候变化与土地利用变化的响应等;从发展趋势来看,中文文献在森林生态系统水源涵养领域研究侧重于枯落物层和土壤层的水文效应,而英文文献侧重于干旱条件、空间变异及景观格局变化对水源涵养功能的影响。整体上,未来我国应进一步注重变化情景下(如气候变化、森林结构变化、土地利用变化等)不同时空尺度水源涵养功能变化及其评估等研究,以期更加有力服务于水资源的综合管理及风险防范决策。

The study of water conservation function and value in forest ecosystems has long been a promi-nent topic in the field of forest ecosystem service function,as forests play a crucial role in preserving water resources in terrestrial ecosystems.This paper aims to investigate the progress,research focus areas,and latest trends in the water conservation function of forest ecosystems.The study utilizes the China Knowledge Network(CNKI)and Web of Science Core Collection database,along with visualization tools such as CiteSpace and VOSviewer.These tools are employed to analyze the knowledge structure of research in this field,as well as the publication dynamics,international and institutional collaborations,prominent topics,and emerging devel-opments.The findings indicate a global upward trend in the publication of articles on water conservation in forest ecosystems,with China′s research in this area gaining increasing international recognition.China leads in terms of the number of published articles,but the United States demonstrates stronger collaboration with other nations.Among the organizations publishing in this field,the Chinese Academy of Sciences has the highest number of publications in both the CNKI and WOS databases.The study′s focal points on water conservation in forest eco-systems,both in Chinese and English,are the forest′s water retention capacity,the ecological services it pro-vides,and how these are affected by climate change and land use change.Chinese literature in the field of water conservation in forest ecosystems primarily examines the hydrological effects of the litter layer and soil layer.In contrast,English literature focuses on the impacts of drought conditions,spatial variability,and changes in landscape patterns on the water conservation function.In the future,China should prioritize research on the changes in water conservation functions and their assessment at various spatial and temporal scales under different scenarios such as climate change,forest structural change,and land use change.This research will enable Chi-na to provide more effective services for integrated water resources management and decision-making for risk prevention.
