To explore the historical evolution and current status of the EwE (Ecopath with Ecosim) modelling research, the core dataset and extended dataset were collected by topic retrieval and citation indexing methods from the "Web of Science" from 1984 to 2020. The bibliometric analysis and mapping knowledge were performed by CiteSpace software, focusing on literature distribution, research forces, research theme, and hotspot evolution. The results showed that the annual publications in the EwE model researches were increasing, covering multi-disciplinary fields. Christensen, Walters, and Pauly were representative scholars with an important role in model development and relevant international cooperation. In the early stage, EwE model was usually applied to solve ecosystem problems, including spatial-temporal dynamic of structure and function, and the ecosystem effects of fisheries. Currently, marine resource management, ecosystem modelling, marine protected areas and ecosystem indicators had become the key themes. The research hotspots shifted from model development and food web structure to ecosystem forecasting and resource management, which would provide scientific evidence for ecosystem-based aquatic resource management and the construction of protected area in marine.
为探究EwE(Ecopath with Ecosim)模型的历史演变和应用现状,本文通过Web of Science主题检索和引文链接法获得1984—2020年间的研究文献构成核心数据集和扩展数据集,并以此为数据源,从论文分布、研究力量、研究主题、热点演化等方面进行科学文献计量分析,利用CiteSpace软件绘制相关图谱。结果表明: EwE模型的系列研究成果产出总体呈上升态势,且广泛分布于多学科交叉领域, Christensen、Walters、Pauly等学者在模型应用和国际合作中起到重要推动作用。过去,EwE模型通过建立功能组间的营养关系,主要用于解决生态系统结构和功能的时空变化、捕捞对生态系统影响等问题。当前,研究主题聚焦于海洋资源管理、生态系统模拟、海洋保护区、生态系统指标等重点群组。研究热点从模型开发和食物网结构向生态系统预测和资源管理研究演变,从而为基于生态系统的水域资源管理和海洋保护区建设等提供科学依据。.
