摘　　要：基于河流水环境系统的随机、模糊与灰色等不确定性,将水环境系统参数定义为区间数。在此基础上,通过将常规的确定性模型参量区间化,建立了河流水环境容量计算区间数模型。根据该模型,可以计算得到河流水环境容量区间值。结合渭河关中段实例研究表明,基于区间数理论计算河流水环境容量,理论上可行,计算结果可信。Based on the characteristics of random,fuzziness and grey of water environmental system,the parameters of river water environmental system were defined as interval numbers. On the basis,an interval number model for calculating river water environmental carrying capacity was es-tablished through interval analysis the parameters in the conventional and certain model. From the model proposed above,the interval value of river water environmental carrying capacity was derived. The result of Central Shaanxi Reach of Weihe River shows that it is feasible in theory to utilize the interval number theory to calculate the carrying capacity of river water environment.
