在“双碳”目标下，贵州省面临氢能“产销分离”与山地丘陵地形的双重约束，单一公路运输方式经济性差、安全风险高，亟须构建适应复杂地形的氢能多式联运体系。本研究采用理论分析与定量评估相结合的方法，首先，从理论必然性与现实需求性出发，论证发展氢能多式联运的战略逻辑；接着，系统评估贵州省氢能相关政策、资源禀赋、交通基础设施现状及关键瓶颈；进而构建了“枢纽—通道—模式—政策”四维联动的氢能多式联运体系，包括“一级氢源枢纽—二级中转枢纽—三级应用节点”布局，设计公路主导、铁路补充、水运辅助、管道远期储备的通道体系，提出“公路+铁路”“公路+水路”“氢能重卡+集装箱”3种联运模式。最后，对典型通道进行测算，结果显示，与单一公路运输相比，公铁联运单位成本降低约60%，公水联运降低约14%。研究表明，构建多式联运体系是贵州省突破氢能储运瓶颈、实现安全稳定大规模氢能供应的必然选择，并可为我国西部类似地形地区提供理论与实践参考。

Under carbon peaking and carbon neutrality goals, Guizhou Province faces the dual constraints of disconnection between hydrogen production and consumption and its mountainous and hilly terrain. Given that road transport alone is economically inefficient and poses high safety risks, there is an urgent need to establish a hydrogen multimodal transport system adapted to the complex terrain. This study adopts a combination of theoretical analysis and quantitative evaluation, demonstrating the strategic logic for developing hydrogen energy multimodal transport from the perspectives of theoretical necessity and practical necessity firstly. Next, it systematically assesses hydrogen energy-related policies, resource endowments, current status of transportation infrastructure, and key bottlenecks in Guizhou Province. And then, a four-dimensional, integrated hydrogen multimodal transport system—linking "hubs, corridors, modes, and policies"—is designed. It includes the layout of "first level hydrogen source hub-second level transit hub-third level application node", the design of a channel system dominated by highways, supplymented by railways, assisted by water transport, and reserved for future by pipelines, and three intermodal transportation modes of "highway+railway", "highway+waterway" and "hydrogen heavy truck+container". Finally, the calculation results of typical channel show that: the unit cost of road-rail intermodal transport is reduced by about 60%, and the unit cost of road-water intermodal transport is reduced by about 14% compared with single road transport.The research indicates that building a multimodal transport system is an inevitable choice for Guizhou to break through bottlenecks in hydrogen energy storage and transportation and achieve safe, stable, large-scale supply of hydrogen energy. It can provide theoretical reference and practical paradigms for similar terrain areas in western China.
