This study focuses on the global ecological crisis exacerbated by traditional exhibition hall education inefficiency. Based on modular design theory and multimodal interaction technology, a green natural theme containerized exhibition system is constructed. Through quantitative analysis of 200 valid questionnaires and field surveys in typical exhibition halls in Beijing, the urgent demands for immersive interactive experiences and sustainable exhibit forms among visitors are revealed. The study proposes a “Modular Carriers - Green Content - Multimodal Interaction” tripartite design model, utilizing recycled aluminum honeycomb panels, bamboo fiber boards, etc., as low-carbon materials. It develops three themes: “Wetland Rhythms,” “Photon Future,” and “Carbon-Free Lifestyle.” Through linear and circular pathways, it achieves spatial narrative logic and visitor experience optimization. Practice shows that the system reduces exhibition preparation cycle by 23% and lowers costs by 36.5%. It also demonstrates resource adaptability in ecological education scenarios in impoverished areas. Future research plans to integrate 5G IoT technology to build a lifelong zero-carbon exhibition system, aiming to provide innovative educational patterns for global sustainable development goals.
