Abstract: Flexible insulated solar greenhouses have gained popularity in Beijing due to their advantages such as prefabricated structures, high land utilization rates, and rapid construction, emerging as a significant development direction for facility agriculture．However, solar greenhouse environmental regulation technologies remains in preliminary exploration stage．Based on flexible solar greenhouses' characteristics, an intelligent environmental regulation technology system for flexible insulated solar greenhouses were established．Experimental demonstrations were conducted in Miyun District, Beijing City, automatic control of greenhouse environmental has been basically achieved．Additionally, an automatic control experiment for upper vent ventilation was implemented．Results showed that compared to traditional greenhouses relying on manual operation, system significantly improved temperature stability and resistance against extreme weather conditions．
