Based on the natural characteristics of storm surge such as concentrated occurring time, significant regional differences, severe economic losses and serious secondary disasters, and on the analysis of the relief demands of the masses, government and economic organizations, this paper dissects the synergetic mechanism between losses and relief of storm surge from dimensions of time, space and logic. A fourdimensional relief system is constructed, containing content system, structure system, hierarchical system and service system. This paper suggests operating the system efficiently by accelerating the building of legal system, improving financial investment mechanism and constructing the supervision system.
