Abstract: Intelligent facility horticulture aims to apply modern technology in facility agriculture production and realizes automation, digitalization, networking, and intellectualization of production．To comprehensively understand research trends, frontiers and hot topics of intelligent facility horticulture in domestic and foreign countries, bibliometrics methods and core papers retrieval platform in Web of Science were used to analyze global research trends, main research contents, and frontier hot spots from 781 research literatures in field of intelligent facilities horticulture from 2002 to 2022．Results showed that intelligent facility horticulture had developed rapidly after 2017, with several publications from 2018 to 2022 accounting for 74.56% of the total number of publications．In general, intelligent facility horticulture presented an interdisciplinary research direction led by agronomy and engineering, top five countries with the largest number of publications were China, the United States, South Korea, Spain, and Italy．China Agricultural University, Ministry of Agriculture and Rural Affairs of the PRC, Chinese Academy of Sciences, Nanjing Agricultural University, and Beijing Academy of Agriculture and Forestry Sciences ranked among the world's top 15 in terms of publications, accounting for 32.34%．Through cluster analysis, intelligent facility horticulture research focused on water and fertilizer control and robotic operation based on automation technology, crop growth monitoring based on internet of things monitoring coupled with machine learning and vision, and greenhouse energy management system research．Among them, computer vision was a technology involving pattern recognition, image processing, and machine learning to realize crop growth monitoring, pest and disease identification, and quality monitoring in facility horticulture, which is a frontier hotspot in intelligent facility horticulture research．
