The invention discloses an uncertainty analysis method for basin non-uniform design flood under changing conditions. The method mainly comprises the uncertainty influence of climate changes and humanactivities on non-uniform design flood is analyzed by combining a basin hydrological simulation technology, an uncertainty analysis technology and a non-uniform hydrological frequency analysis method,therefore, the uncertainty interval of the non-consistent peak value joint design value under the specified probability is obtained, the reliability of the non-consistent design flood result is improved, and reference is provided for decision makers of basin water resource planning management and flood control scheduling. 本发明公开了一种变化条件下流域非一致性设计洪水的不确定性分析方法。主要包括：通过结合流域水文模拟技术、不确定性分析技术、非一致性水文频率分析方法分析气候变化和人类活动对非一致性设计洪水的不确定性影响，从而得到非一致性峰量联合设计值在指定概率下的不确定性区间，提高非一致性设计洪水结果的可靠性，为流域水资源规划管理及防洪调度的决策者提供参考。
