摘　　要：基于河流水环境系统的不确定性,将水环境系统参数定义为三角模糊数,通过将常规的确定性模型参量用三角模糊数表示,建立了河流水环境容量计算的三角模糊数模型。根据该模型,可以计算得到河流水环境容量的三角模糊数值。结合渭河关中段实例研究表明,基于三角模糊数理论计算河流水环境容量,理论上可行,计算结果可信。Abstract： Based on the uncertainty of river water environmental system, the parameters of water environmental system were defined as triangular fuzzy numbers. Through using the triangular fuzzy number to express the parameters of the conventional and certain model, this paper established a triangular fuzzy number model to calculate river water environmental carrying capacity. According to this model, the triangular fuzzy number of river water environmental carrying capacity was derived. The case study result of central Shaanxi reach of Weihe River shows that it is feasible in theory to utilize the triangular fuzzy number theory to calculate the carrying capacity of river water environment and the calculation result is reliable.
