摘　　要：本文通过对黄河干流节点径流频率分析和超越机率分析,推求了节点水文缺水量。通过制定黄河干流水文缺水等级划分标准,用节点天然径流系列为样本,建立了节点水文缺水分类模型。应用分类模型,进一步得到了节点缺水状态转移概率矩阵。节点水文缺水分类模型和状态转移概率矩阵将会对黄河干流水资源合理配置提供决策依据。Based on the frequency analysis and exceed probability analysis of Yellow River node＇s runoff, the node＇s hydrology water shortage was calculated. Further a hydrology water shortage degree rule and a classification model were presented. Using the classification model, the hydrology water shortage situation change probability matrix was brought forward. It was helpful for water resources rationalization distribution of Yellow River.
