摘要
由于水体水环境系统信息的不确定性,因此运用未确知数学理论,对未确知信息下的水库水环境容量进行计算。由水库水环境容量的计算公式,依据未确知有理数的运算法则和未确知数学的期望公式,求得水库水环境容量的期望值,还可以获得相应的主观可信度。研究表明,运用未确知数学计算不确定性信息下的水库水环境容量,理论上可行,计算结果可信,为水质管理和保护提供了科学依据。
Because of the unascertained information in the reservoir water environmental system,a calculation is made on the water environmental capacity by the use of unascertained mathematics theory. Based on the calculation formula of reservoir water environmental capacity and the rules of four fundamental operations of unascertained rational numbers we can obtain not only the reservoir environmental capacity but also its corresponding confidence level. The case study shows that unascertained mathematics theory has a wider application prospect in water quality managing and environmental protection fields.
