Information Entropy Analysis on Nonuniformity of Precipitation Dist ribution in Time-Space, Ⅰ, Basic Concept a nd Data Analysis

  • 摘要: 介绍了熵的基本概念及性质,并对熵的各种算法进行了比较分析.由熵的空间分布状况,研究了信息有向传输问题,初步揭示了降水在空间分布的结构特征,得到了一些符合实际的结论.研究显示,利用熵来分析水文水资源中的不确定性是一种有效的方法.

     

    Abstract: The basic concept and several characteristics of entropy are introduced,and the different computing metheds on entropy are compared. Based on the spatial distribution of entropy,the paper studies the directional information transfer index between gauged stations,with which the spatial construction of precipitation distribution is revealed,and some natural conclusions are obtained.According to the studies,it is one of effective roads to use the entropy to research uncertainty in hydrology and water resource.
