A Study on the research hotspots and emerging trends of international agroecology based on WOS
-
摘要: 农业生态学作为生态学和农业科学的交叉学科, 有助于优化传统农业体系和生态农业实践。为厘清国际农业生态学的发展现状和研究趋势, 本文借助CiteSpace对2012—2021年Web of Science核心数据库的国际农业生态学论文进行计量分析, 研究发现: 第一, 国际农业生态学的热点议题主要关注作为农业生态系统的整体表现及其评价的研究、以生态农业实践为基础的科学研究以及关于生态农业社会运动与社会影响的研究等方面。第二, 国际农业生态研究人员在农业生态学领域有很多基础性和创新性研究, 主要围绕农业生态转型与生态农业产业形态、生态农业社会运动以及如何调节农业生态系统内部诸生态因子建构可持续农业生态体系展开。第三, 国际农业生态学研究的前沿趋势不仅聚焦于涉及自然学科的生物多样性保护、景观生态安全格局、农业种植体系与农药污染等内容, 还涉及社会管理相关领域的知识农民培育、农业教育和参与式治理模式等方面研究。未来国内农业生态学的发展可在立足国情的基础上, 加强国际交流合作, 同时, 紧随国家发展战略, 从而推动新型农业技术的创新发展。Abstract: In recent years, with continuous changes of the ecological environment, there is a general public perception that promoting the coordinated and sustainable agriculture is much higher than the development of extensive, industrial as well as single-oriented agriculture. Agroecology, as an interdisciplinary science of ecology and agricultural science, provides a channel to optimize conventional farming systems and ecological agriculture practices, thus becoming thriving research hotspots in the present day. Therefore, clarifying the research hotspots and emerging trends of international agroecology research helps explain its development and prospect, while there is little in-depth research on this topic. Thus, this study employs the visual analysis software CiteSpace to conduct a bibliometric analysis of the relevant literature on the international agroecology research in Web of Science from 2012 to 2021. According to the study, three points stand out. The first point is concerned with research hotspots of studies on international agroecology. Specifically, through the analysis of 19 keyword clusters, it shows that the research hotspots focus more on the agro-ecosystem’s overall performance and evaluation, for example, the investigation on irreversible influences of climate change, the optimization of climate resilient system along with the improvement of field. Besides, the fundamental and scientific research of ecological agriculture practice gains extensive scholarly focus, in particular, the study on agricultural intensification, integrated weed management, soil organic matter and plant function trait etc. Additionally, the social movement of ecological agriculture with its social influence on food security and food sovereignty have been widely investigated. The second point centers on the basic knowledge of studies on international agroecology. Via a detailed account of highly cited reference and references co-citation clustering network, the knowledge base reflects that international agroecology scholars have done many basic and innovative studies in this field. Notably, the related knowledge base dwells on the ecological transformation of agriculture and the industrial form of ecological agriculture, the social movement of ecological agriculture, as well as how to adjust the ecological factors embedded in agricultural ecosystems (e.g. crop diversification, diverse cropping systems and plant patterns) to construct a sustainable agro-ecosystem. The third point relates to emerging trends of studies on international agroecology. Based on burst words and references with subsequent citation burst, emerging trends highlight more on agrobiodiversity, biodiversity conservation, landscape ecological security pattern, production system and pesticide pollution within natural sciences. Meantime, it also involves the research of social management field, specifically, the cultivation of knowledgeable farmers, agricultural education and the connection between indigenous knowledge and modern agro-ecological practices on the basis of participatory action research. As for the significance of the study, this paper contributes to mirroring the research hotspots and emerging trends of international agroecology, thus giving readers a guidance to probe into how the research foci, knowledge base along with research front of international agroecology research change. Moreover, rooted in the national conditions, the future development of domestic agroecology can strengthen international exchanges and cooperation, follow international hot research topics; meantime, future research can keep in step with the national development strategy and boost the advancement of new agricultural technology, thus enhancing the diversity and sustainability of agro-ecosystem.
