模糊综合评价法在宝鸡渭河两断面水质评价中的应用

摘要

Fuzzy comprehensive Evaluation was used to evaluate the water quality of Wolongsi and Changxingqiao sections of Wei River during the 2006 -2010 years. Three indexes were determined to be the evaluation factors, and the membership function was built up. A clear result was achieved on the base of measured data. The results indicated that the water pollution situation during 2008 - 2010 was better than the 2006 -2007 in both of the two monitoring sections.%采用模糊综合评价法对“十一五”期间（2006—2010年）宝鸡市渭河2个国控断面（卧龙寺和常兴桥）水质进行了评价，确定了3个指标作为评价因子，建立了隶属函数表达式，并根据渭河实测的数据，取得清晰的评价结果。结果表明：2008—2010年卧龙寺和常兴桥污染状况较2006—2007年有所改善。
