This study focused on water quality in 11 typical sections of Shaxi River

Minjiang River basin and developed an attribute recognition model by applying attribute recognition theory and attribute recognition guild lines.Results showed that water quality in 8 sections was up to the third class of the national water quality standard of China

which may be considered as drinkable water resource.By contrast

water quality in other 3 sections did not reach the third class of the national water quality standard.The result was similar to that from the analysis of fuzzy membership function.It demonstrated that the method of attribute recognition model was suitable for assessing water quality.Finally

according to the absorbency values of 11 water samples under 254 nm

mineral matter was the dominant pollutant.
