摘　　要：通过对河流的主要污染物耗氧有机物的特点的分析,总结了耗氧有机物进入河流后的运动特征,阐述了在稳态条件和忽略弥散作用下,污染物的一维水质模型.另外,在此基础上论述了河流稳态水质模型建立的条件及S-P的数学模型.最后经分析复氧曲线、耗氧曲线和氧垂曲线的内涵,提出了研究河流水质模型的意义.By the analysis of the features of the major pollutants and oxygen - consumed organic compound in rivers, this paper summarized the motional features of the oxygen - consumed oxygenic compound after it runs into rivers, and expound that under steady conditions and neglecting the spreading effect, there is a one -dimensional water quality model of pollutants. In addition,on the basis of this, this paper also discussed the conditions on which the steady water quality modal of rivers can be built and the mathematical modal of s- p. At last, though the analysis of the connotation of oxygen - added curves, oxygen - consumed curves and oxygen - dissolved curves, the paper raised the meaning of investigating the water quality modal in rivers.
