One-dimension inundated area series is developed to multi-dimension inundated area series with reconstruction of phase space , and the multi-dimension series include ergodic information , so that more abundant information can be found in favor of ann training .

通过相空间重构，把一维成灾面积时间序列拓展为多维序列，而多维序列包含着各态历经的信息，从而可挖掘更为丰富的信息，有利于神经网络的训练。
