摘要
河流系统存在一定的不确定性。设计流量的确定对于水环境容量的计算具有决定作用。将未确知理论引入水环境容量计算,采用未确知理论中未确知有理数概念,将设计流量作为未确知有理数,分别计算其不同情况下的取值可能值以及可信度。以山东省小清河济南段为例,计算得到90%设计流量下水环境容量的区间值及其对应可信度,旨在更充分的了解小清河水环境容量的实际情况,为水环境治理提供更科学的依据。
River system has certain uncertainty.Determination of design flow is crucial to the calculation of water environment capacity.Uncertainty theory was introduced into water environmental calculation in the paper.It took design flow as a unascertained rational number,and calculated the value and its probability in different situations.Taking Jinan section of Xiaoqinghe in Shandong Province as example,it calculated the interval value and corresponding credibility under 90% design frequency by using unascertained rational number to ascertain practical situation of its water environment capacity.The result can supply scientific basis for water environment treatment.
