摘　　要：针对现有盲数理论的不足,采用三角模糊数替代盲数中的区间数,构造了一个能够综合处理随机信息、模糊信息、灰信息和未确知信息等复合信息的新盲数,即延拓盲数.在此基础上,通过将水环境系统参数定义为延拓盲参数,建立了河流水环境容量计算延拓盲数模型.实例研究表明,以包含三角模糊数的延拓盲数计算河流水环境容量,理论上可行,计算结果可信.Aimed at the problem that the current blind number theory cannot deal with fuzzy information, an extended blind number was proposed by using a set of triangular fuzzy numbers instead of grey interval values in the traditional blind number. By defining the parameters in water environmental system as extended blind numbers, a new model with extended blind parameters was then established for calculating the carrying capacity of fiver water environment. The result of a case study shows that it is feasible in theory to utilize the extended blind number to calculate the carrying capacity of river water environment.
