摘要
以新疆和田地区地下水质量评价为例,用可拓分析方法将地下水质量级别、评价指标及其特征值作为物元,根据地下水环境质量分级标准建立关联函数,通过计算关联度判断该地区地下水环境质量级别,经与模糊综合分析法比较,表明评价结果与该地区客观实际基本吻合。
A technique for synthetic valuation on ground water quality of Hetian, Xinjiang by using extension method is proposed. The grade of ground water quality, index of evaluation and its characteristic value are taken as matter elements. Correlated function is established based on the grade of ground water quality and then the grade is judged by calculating the synthetic correlated degree. Compared with Fuzzy comprehensive appraisal,the results accord with actual status in the evaluated area.
