水文频率线型选优的最小信息熵准则

Criterion of Minimum Entropy for Optimizing the Hydrologic Frequency Distribution

根据信息熵的基本概念，提出了最小信息熵准则作为水文频率线型选优的判别标准，给出了推导频率分布信息熵的一般方法，及各种信息熵的计算公式。

On the basis of the information entropy concept,the criterion of minimum information entropy is prososed as a standard for optimizing the hydrologic frequency distribution in the paper.In view of the demand for calculating the entropy values,we also give the generalized derivation method of the information entropy and the information entropy formula of some useful hydrologic frequencys.Fourteen practical examples are given at last.
