摘　　要：耗氧系数K1是水质模型中关键的参数之一。本文按确定性水质模型和不确定性水质模型分别介绍了5种K1的估值方法,并论述了各自的适用条件和优缺点。其中不确定性K1的估值方法是将耗氧系数和未确知数学相结合后提出的,能为水环境预测和管理的后续工作提供计算依据。Oxygen consumption coefficient K1is one of key parameters in water q uality model. The paper introduces five estimation methods according to deterministic water quality mode l and uncertainty water quality model, expounds suitable condition and merit, sh ortcoming of these methods. The estimazation method of uncertainty K1 is put forward after combination of oxygen consumption coefficien t and unknown mathematics for provide calculation basis of water environment for ecast and management.
