Application of Attribute Recognition Model Based on Coefficient of Entropy to Evaluate Water Quality of Shaxi River in Sanming

Xia Qihua1,Zhang Jiangshan1,Cheng Sheng2(1.College of Chemistry and Materials Science of Fujian Normal Uiversity,Fuzhou 350007,China;2.Fuqing Branch of Fujian Normal University Fuzhou Fujian,Fuzhou 350300,China)  
This paper combine the entropy value theory and attribute recognition model together,which use law of entropy value to calculate coefficient of weight and establish the attribute recognition model that based on coefficient of entropy.Attribute recognition model of source and monitored information of shaxi river in the early year of 2007,the water quality is calculated.The results indicate water quality of Shaxi River in 2007 is better than III water standard of surface water,which compares with water quality of Shaxi River before 2000(before 2000 some places'water quality were lower than III water standard of suface water,especialy in Sanming city),which shows that Shaxi River's water quality situation has had a large improvement in the past several years,and shows that Shaxi River's renovation work had done well.At last we discuss the control countermeasures preliminary.
