The risk assessment of the camp facilities agency in the highland alpine area is a complex systematic project, and its specificity lies in the superimposed effect of the extreme natural environment and complex management needs. For this reason, this study proposes to combine the fuzzy hierarchical analysis method FAHP with the risk identification technology to construct a risk assessment model applicable to this region. Four core risks and 12 sub-risks, including natural environment, logistics, personnel health and technology management, were systematically identified through brainstorming, and the weights of each index were quantified based on FAHP. The experimental results show that the logistic support risk with a weight of 0.334, and the natural environment risk with a weight of 0.262 are the core challenges, of which the material transportation disruption C4 with a weight of 0.124, the extreme climate impact C1 with a weight of 0.163 and the plateau reaction health problem C7 with a weight of 0.071 are the key sub-risks. The fuzzy comprehensive evaluation further indicated that C7, C8 low-temperature exposure health problems and C11 insufficient equipment adaptability have the highest risk level and need to be prioritized for prevention and control. The point degree centrality analysis reveals the strong conductivity of nodes such as C4 and C7, which validates the dynamic risk network characteristics of the model.
