Research Trends Analysis of Modern Agricultural Science and Technology During Recent 10 Years in China Based on Bibliometric and Topic Model

In order to understand and master the research situation and development trend of modern agricultural science and technology during recent 10 years in China comprehensively, this paper analyzed the literature on two important aspects of modern agricultural science and technology in China, namely the botany and botany-related disciplines and animal husbandry & animal medicine discipline based on bibliometric and LDA topic model, including the bibliometric analysis on the trend of published papers, author and research institution, and the topic analysis of research contents. The results showed that these research fields were active and the research contents were consecutive. The research would have certain reference value for the decision-making and development of related research field in China.
