摘　　要：基于河流水系水文、水质的动态特征,以及监测资料信息的不确定性、不完整性,将盲数理论应用于河流氨氮削减量的定量化研究。在对河流水环境系统不确定性分析的基础上,定义了水环境系统盲参数概念,通过将确定性水体纳污能力计算模型中的参量盲数化,建立了盲信息下河流氨氮纳污能力计算模型和氨氮削减量计算模式,并对淮河干流蚌埠段的氨氮削减量进行了计算。实例研究表明,对超标河段氨氮削减量计算问题,所建模型具有很好的适用性。Based on the dynamics of river hydrology and water quality, the uncertain and incomplete characteristics of monitor information, the blind number theory was used to calculate the quantity of nutrient reduced. Through the uncertainty analysis of river water environmental system, the concept of blind number parameter was defined. By way of treating the model parameters as blind numbers, a model for calculation of water environmental carrying capacity and a model for determination of quantity of nutrient reduced were constructed under blind information. As a case, the model proposed upward was used to calculate the quantity of nutrient reduced in Bengbu urban reach in Huaihe river. Case result showed that the model with blind number parameters is suitable for research on quantity of nutrient reduced.
