Abstract: Introducing chaos theory into the floodwater the factor of nature and human society [2]. The
disaster resources field, the forecasting model for the important scale index of the social loss is the
inundated area of flood disaster was brought forward factors: the area, the population and the
integrating reconstruction of phase space and neural economic loss in disaster etc., which is
network. One dimension inundated area series is developed important described ration index in the
many dimension inundated area series with reconstruction subsystem of the situation of a disaster. The
of phase space, and multi- dimension series include the index often appears strong random in
ergodic information, so the more rich information can be distributing time, so the conventional statistical
excavated for ANN training; and the non-linear problem measure can’t open out the uncertain action
