近10年京津冀地区农业科技发展态势分析

［目的］随着京津冀一体化协同发展的深入推进，近年来京津冀地区现代农业的发展在实践和创新中突飞猛进。通过调研分析京津冀农业科技发展现状及近10年农业领域的科技文献，挖掘该地区的农业核心科研机构，判读农业科技热点和新兴技术等发展态势，旨在为京津冀地区未来农业科技发展布局和政策的制定提供信息支撑。［方法］文章分别选取2008—2018年北京市、天津市和河北省的SCI和CPCI论文，运用DDA和VOSviewer等文献计量可视化软件，结合EI算法、Cosine算法和共词分析算法，对比分析3省市的农业科技发展态势。［结果］研究结果表明，在土地、水资源和农业就业人员等条件相对缺乏的情况下，京津冀地区现代农业的发展得益于科技的投入和科研的进步，其中北京市是京津冀地区中对科技高端人才、资源和经费投入最多的地区，在现代农业科技创新研究和科技发展态势方面，生物技术及相关研究是京津冀地区农业领域近年来的研究热点和发展方向。［结论］中央和地方政府应进一步优化京津冀地区的农业发展政策、重点发展领域、科研经费使用和科研机构配置。

ANALYSIS OF TRENDS IN THE DEVELOPMENT OF AGRICULTURAL SCIENCE IN THE BEIJING TIANJIN HEBEI REGION IN PAST TEN YEARS

With the integrated development of Beijing Tianjin Hebei region growing, modern agriculture in the region has made rapid progress in practice and innovation in recent years. Through research and analysis of the current agricultural status and literature of the past decade in Beijing, Tianjin, and Hebei, this paper explores the core scientific research institutions in this region as well as interprets trending research topics and emerging technologies, aiming to provide an informational support for designing the framework of future agricultural development and formulating policies in the Beijing Tianjin Hebei region. The SCI and CPCI papers of Beijing, Tianjin, and Hebei from 2008 to 2018 were selected, respectively. The methods, such as the EI algorithm, cosine algorithm, and co word analysis algorithm in combination, were used to compare and analyze the trends in the agricultural development in the three cities with the help of DDA and VOSviewer analysis, the visualization software tools for bibliometric analysis. The results showed that, under conditions of a relative lack of land, water resources, and agricultural employment, the development of modern agriculture in the Beijing Tianjin Hebei region benefited from the investment in science and technology and the advancement in scientific research. Among the three provinces/cities, Beijing had invested the most in high end talents, resources, and funds. Concerning the innovation and development of modern agricultural science, in recent years, biotechnology and related research were the trending research topics and future directions of agriculture in the Beijing Tianjin Hebei region. The central and local governments should further optimize policies in agricultural development, key areas of development, distribution of research funds, and allocation of resources to scientific research institutions in the Beijing Tianjin Hebei region.
