流域蓄水容量曲线的信息熵理论

Theory of Information Entropy of Storage Capacity Curve of a River Basin

以最大信息熵原理为基础 ,对流域蓄水容量曲线进行了研究 ,并导出了两种具体的流域蓄水容量曲线模型———n次抛物线型与指数曲线型。然后结合其线型的信息熵应满足的约束条件 ,对n次抛物线型与指数曲线型流域蓄水含量曲线的适应性进行了分析和讨论。

Based on the principle of maximum information entropy,the research on storage capacity curve of the river basin has been carried out and two concrete models of storage capacity curve of the basin--parabolic model of n order and exponential curve model have been derived.Analysis and discussion have been conducted on the adaptability of storage capacity curves of the above two types in combination with the restraint conditions which should satisfy the information entropies of each types.
