This paper is concerned with the problems that extension method is used in water quality assessment. At first, the way is recommended to build the matter-element model of comprehensive assessment on water environmental quality. Then, six commonly measured water quality variables are selected as evaluation parameters, including dissolved oxygen, chemical oxygen demand, permanganate index, nitrite nitrogen, nitrate nitrogen and total phosphorus. The model was utilized to evaluate water quality of the water intake of the Yellow River in Zhengzhou, China. The evaluated results obtained from the matter-element model was the same as the fuzzy comprehensive assessment. Through the case study, this paper also has analyzed the characteristics of the matter-element model, in addition, the sensitivity analysis about dissolved oxygen parameter has carried out and showed that dissolved oxygen was not sensitive parameter in this case.
