目的 研究我国肉羊产业发展现状并分析热点，为肉羊产业的可持续发展提供数据支持。 方法 以“肉羊”为主题的相关文献作为研究对象，基于 CiteSpace 6.3.R1（64 bit）文献计量软件，对CNKI（中国知网）期刊数据库中EI、北大中文核心、CSCD及CSSCI来源论文进行知识图谱的绘制并进行研究分析。 结果 国内肉羊产业发展研究的文献发表量呈上升趋势，发表量最大的学者为刁其玉，发表量最大的机构为中国农业科学院饲料研究所/农业农村部饲料生物技术重点实验室。研究机构分散，不同研究机构在研究领域和方向等方面存在较大差异；肉羊产业发展研究主要围绕肉羊性能、肉羊品种及产业效益等3个方面；研究热点演进经历了从肉羊的繁殖、饲养管理、品种到肉羊的经济效益、健康管理、生产性能，再到产业发展、绿色健康养殖、产品推广等各个方面的发展。 结论 研究热点发生了3次大的转变：从宏观到微观，从整体到局部，从只顾生产到环境与效益的兼顾。产业模式和产业技术创新研究为两大研究热点。

Objectives The current status of developing mutton sheep industry in China was studied and the research hotspots were analyzed to provide data support for the sustainable development of the meat sheep industry. Methods A knowledge map of relevant literatures with the theme of " mutton sheep" from EI, Peking University Core, CSCD, and CSSCI sources in the CNKI journal database was drawn and analyzed based on CiteSpace 6.3.R1 (64 bit) bibliometric software. Results The number of literatures published on the development of mutton sheep industry in China is increasing, with Diao Qiyu being the scholar with the highest number of papers, and the Institute of Feed/Ministry of Agriculture and Rural Affairs Key Laboratory of Feed Biotechnology, Chinese Academy of Agricultural Sciences being the institution with the highest number of papers. Institutions are scattered, with significantly different research fields and directions. The studies on the development of mutton sheep industry mainly focused on three aspects including the performance, the breeds of mutton sheep, and the industrial benefits. The research hotspots have evolved from aspects including the reproduction, feeding management, and breeds of mutton sheep to their economic benefits, health management, and production performance, and further to industrial development, green and healthy breeding, and product promotion. Conclusions The research hotspots have undergone three major shifts: from macro to micro, from holistic to partial, and from focusing solely on production to balancing both environment and benefits. Studies on the models and technological innovation of industry are two major research hotspots.
