| 摘 要： | 基于系统论和信息论，提出了滑坡体稳定性分析预测的信息熵方法；首先将影响滑坡因素的时间序列观测值转换为概率化序列值，然后计算它们的总归一化信息熵值；从总归一化信息熵值的变化中发现，滑坡发生前后，熵值有一个陡增锐减过程．因此，可以根据滑坡体熵值的变化分析预测滑坡体的稳定性。

| Abstract: | Based on system theory and information theory, proposed a novel analyzing and forecasting approach of landslide, that is, information entropy approach. First of all, the time serial surveying data of landslide-factors were transformed into probability serial data, and then the total information entropy of these factors were evaluated by these probability serial data. From the change of information entropy, it can be seen that there is a sharp increase and decrease of information entropy before and after landslide occurs. So, the occurrence of landslide was forecasted according to the change of information entropy. |
