摘　　要：引入信息融合理论,通过在系统输入变量上叠加"干扰流量",基于对灌区用水模糊特征分析估计其不确定性,实现分散且孤立的实时监测数据之间的关联,使系统保持必要的信息冗余,进而实现灌区水情信息融合。该方法可用于建立具有跟踪和预测能力的灌区实时仿真系统,克服了信息融合理论用于非线性时变系统的诸多限制,扩展了信息融合理论在系统关系确定的民用领域的应用。A method for the water information integration of irrigation district was introduced. Irrigation hydrological information integration was achieved by imposing perturbation flow on the input variables of system and estimating the uncertainty based on the analysis of irrigation water fuzzy characteristics and as- sociating the data between the dispersed and isolated real-time system in order to maintain the necessary in- formation redundancy. This method could be used to establish the simulation system which traced and forecast the irrigation area water resource, got over the limitations of information integration theory for nonlinear time-varying system, and extended to the civilian areas.
