AN APPROACH OF THE FUZZY SET THEORY IN GROUNDWATER QUALITY ASSESSMENT

Duo Chaomei Jiangxi Environmental Geologic Team  
This paper makes an attempt in the application of the Fuzzy Set Th--eory in groundwater quality assessment.The pollution level of groundwateris represented in several indexes, while the grade of groundwater qualityis determined by the biggest index. Therefore, fuzzy events such as pollu-tion level are described on a more reasonable basis.Quadratic curve is usedas the subordinate function model. The result of practical calculation issatisfying .In addition,the method used in this paper is compared with otherconventional methods. Suggestions on weighting calculation are presented. A BASIC programme for calculation is also attached.
