奎屯市地下水环境背景值及环境质量评价

The Background Values of the Ground Water Environmeit and the Evalua Tion of its Quality in Kuitun City of Its Quality

运用模糊数学理论方法,依据样品中有关评价因子的实测值.对奎屯市地下水进行背景值统计分析,评价各因子对环境质量的贡献,在单因子模糊评判的基础上,对样品隶属于各级地下水环境程度作出综合评判。

The paper makes census and analyses of kuitun city in ground water environmental background values, and applying to the theory and methords of fuzzy mathematics, according to the practical dates of evaluating factors in water sample analyses, utilizing appropriate judging rules in different contribution envirommental quality levels, considering three evaluating factors different contribution to the water environmental quality, and onthe basis of passing fuzzy judgement on single factor, properly and reasonably pass syn-hetic judgement on the degree that the water samples are subordinated to different groundvater enviromental grades.
