Abstract: To promote urban modern agriculture high-quality development and address core issues in facility horticulture production and management, such as low coordination efficiency, difficulties in adopting intelligent equipment, weak data-driven capabilities, and insufficient professional service support, an intelligent technology system for facility horticulture has been established．This system is grounded in Beijing's positioning as a leading hub for facility horticulture and integrates new generation information technologies, including internet of things, big data, and artificial intelligence, to construct a closed loop technical framework centered on perception, decision, execution and service．By developing a newly developed comprehensive digital management and control platform for agricultural parks, innovative IoT monitoring equipment, intelligent control terminals, and a series of algorithm models, a three-level technical solution has been established．This solution covers entire supply chain of "people, finances, materials, production, supply, and marketing", and includes digital management, facility environment monitoring and early warning, and intelligent, precise environmental control．This research provides a replicable and scalable systematic solution for intelligent transformation and upgrading of facility agriculture in metropolitan suburbs．It holds significant practical importance for enhancing industrial competitiveness, ensuring a stable supply of "vegetable basket", and promoting rural revitalization．
