盲数理论在湖泊水环境容量计算中的应用

Application of blind number theory in calculating water environmental carrying capacity of lakes

借鉴已有确定性模型成果,首先建立了一个参量为灰区间数的湖泊水环境容量计算模型。然后从湖泊水环境系统多种不确定性共存的角度,运用盲数理论定义了水环境系统参量盲数。在此基础上,通过对上述包含灰区间数的水环境容量模型参数盲数化,得到了盲信息下湖泊水环境容量计算模型,并给出了大型浅水湖泊水体纳污能力计算方法。实例研究表明,以盲数理论研究湖泊水环境容量,理论上是可行的。

A model for calculating water environmental carrying capacity of lakes is established based on the deterministic theory. In the model the relevant parameters are located in the grey interval. Then the blind number theory is applied to define the blind numbers of the parameters of environmental system according to the characteristics of several kinds of uncertainties coexisting in water environmental system.On this basis, a new uncertain model for calculating water environmental carrying capacity is proposed by means of transforming the grey interval value parameters into blind number parameters of the model.Application shows that the proposed model is feasible and reliable.
