摘　　要：基于河流环境系统信息的未确知性,运用未确知数学理论,建立了一维河流突发性排污的水质模型。该模型运用未确知数学理论进行了含有两个未确知参数的水质计算,不仅可以得到控制断面污染物浓度分布区间及其相应的可信度值,而且可以进行水质风险超标分析。实例研究表明,建立的未确知信息的水质模型是可靠的,可以用于河流水质治理工程的数值模拟研究和水环境评估。Based on the unascertained characteristic of fiver water system, water quality model for one-dimensional sudden pollutant discharged is established by using unascertained mathematics theory. The model is computed basing on unascertained mathematics theory and including two unascertained parameters. According to the model proposed, not only the interval values of pollutant concentration and the respective corresponding faith degree can be obtained directly, but also the analysis of risk for contaminant exceeding the standard value can be done. Sample shows that unascertained water quality model is reliable and can be applied to water quality regulation project and water environmental assessment.
