摘要
灾害以最无序的方式在各地发生,意味着灾害熵达到了极大值.在给定的约束条件下,当灾害熵取极大值时,灾损系列服从P-型分布.灾害损失的重现期指未来某一程度的灾害损失出现的平均时间间隔.根据实测的灾害资料,利用P-型分布函数,计算了未来具有一定重现期的灾害损失大小.这种方法概念明确,便于应用,具有重要的现实意义.
Disaster arises in the form of highly disorder in different area, which means that disaster entropy has gotten maximum. Disaster loss is an P - Ⅲ distribution in given restrained conditions when disaster entropy has gotten maximum. The recurrence interval of disaster loss is the average time interval of arising disaster loss of some degree in the future. In accordance with the measured data of disaster, P - Ⅲ distribution function is used to estimate the magnitude of disaster loss of certain recurrence interval in the future. This method is of a clear concept and easy to use, which is of actual significance.
