基于文献计量的畜禽养殖废弃物新污染物研究态势分析

近年来畜禽养殖行业抗生素、激素等新污染物受到广泛关注，本研究利用CiteSpace软件对畜禽养殖废弃物新污染物的研究动态进行文献计量分析，得出了该领域的研究态势、热点和知识主题演化历程等，并提出下一步研究的重点方向与控制对策建议。研究发现，畜禽养殖废弃物新污染物的相关研究近年来呈现出发文量高速增长的趋势，我国和美国在该研究领域影响力表现突出；以抗生素和激素类为主的新污染物的来源、环境行为归趋和分析检测技术等方面是该领域主要的研究热点；新污染物的潜在生态环境与健康风险研究将成为未来重点关注的方向；在污染防控方面，建议强化对养殖业投入品使用和养殖废弃物处置及排放的监管，并对畜禽养殖新污染物减排和控制关键技术及工程应用的研究加大投入。

Research trend of emerging contaminants in livestock and poultry wastes based on bibliometric analysis

Emerging contaminants, such as antibiotics and hormones, in the livestock and poultry breeding industry have attracted wide attention in recent years. This study conducted a bibliometric analysis of the research dynamics of emerging contaminants in livestock and poultry wastes using CiteSpace software, and obtained the research advances, hot topics, and evolution of knowledge in this field. The research in this field showed a trend of rapid growth in recent years, and China and the United States had a prominent influence. The sources, environmental behavior, and analytical techniques of emerging contaminants(mainly antibiotics and hormones)were the popular research topics in this field. Research on the potential ecological and environmental health risks of emerging contaminants would be the focus of future research. It is recommended to strengthen the regulation of inputs used in the livestock industry, control the disposal and discharge of livestock wastes, and increase the investment in key technologies and demonstration projects for the reduction and control of emerging contaminants in the livestock and poultry breeding industry.
