| 摘 要： | 为了改进传统水文比拟法在相似流域选择上存在的不足，提出一种基于贝叶斯公式的随机分析方法。通过计算设计流域与备择参证流域对应的多个特征指标相似的加权概率，利用最大似然分类的原则，确定加权概率最大者对应的参证流域为所选择的相似流域。通过实例计算分析，并与灰关联分析法、模糊优选法进行比较验证，结果有效的说明了该方法的可行性。 |
| 关 键 词： | 水文比拟法 相似流域 贝叶斯公式 随机分析方法 不确定性 |

| Abstract: | In order to overcome the shortcoming of conventional hydrologic analogy on choosing similar basin,a stochastic assessment method is developed and applied based on Bayes formula.By computing the similar weighed probability of multi-character indices between design basin and benchmark basins,the reference basins of maximal weighed probability will be chosen as the anticipant similar basin based on maximum likelihood clacification principle.Tested by example together with the other two methods,i.e.the fuzzy assessment method and gray assessment method,the results verify effectively that this method is useful and feasible. |
| Keywords: | hydrologic analogy hydrologic similar basin Bayes formula stochastic assessment method uncertainty |
