The equitableness to long-distance of the disaster reduction aims at improving the bad condition of some structural parts, and seeking optimization of the whole system.Under certain constraints, by partition and deformation of the territory, localization of the center and the corresponding long-distance operation mechanism, the disturbance of the disadvantage factors to the system may be reduced, the bottleneck can be technically eliminated, expectation and achieving-degree of the technical indexes in a weaker condition can be improved.The equitableness to long-distance can remedy system's flaw by the long-distance mechanism or construct the complete system in an incomplete condition, safeguard the interest of the whole and the far effect, scientize the disaster reduction management, and improve the disaster reduction work in each aspects.
