Abstract: Critical infrastructure protecting is an important part of emergency management, and determining risk and protecting order is the basis of protection mechanism. With the threat of natural disaster, exceeding probability of information diffusion theory is introduced into the risk model to study the cascade effect risk of network about trans-regional critical infrastructure. Further a method is propased to determine the degree of risk and protect order about critical infrastructure network. Taking power grid with ice disasters for example, the risk of network cascade effect is studied, and the rationality of regarding this kind of risk to be as protection reference is verifed.

Key words: nature disaster, critical infrastructure, risk identification, complex network, cascade effect
