摘要
选取硫酸盐、总锰、总铁、硝酸盐、亚硝酸盐、氟化物、总硬度作为水质的影响因子,将层次分析法和熵权法相结合进行权重计算,结合模糊数学法对吉林市地下水水质进行评价,并将评价结果与内梅罗指数法和传统模糊数学法评价结果进行对比。结果表明:组合权重模糊数学法计算得到的水质等级与其他两种方法计算结果较为接近。采用组合权重模糊数学法对地下水水质进行评价,其中熵权法综合考虑了所有水样数据所包含的信息进行权重计算,层次分析法基于专家打分构建判断矩阵进而确定权重,将主观因素和客观因素均融入水质评价中,评价结果更为客观合理、更具有说服力。
The sulfate, total manganese, total iron, nitrate, nitrite, fluoride and total hardness were selected as the impact factors of ground-water quality, AHP and entropy were combined to weight to calculate the weight. And then the groundwater samples in Jilin City were evaluated by using fuzzy mathematical method and compared with the Nemerow and traditional fuzzy mathematics methods. The results show that the grade of water quality obtained by combination weighting fuzzy mathematical method and the calculation results calculated by the other two methods are closer. The method of combination weighting fuzzy mathematics is selected to evaluate groundwater quality, the entropy weight method considering all water samples information, AHP determining the weight by constructing judgment matrix which is based on experts scoring, subjective and objective factors are integrated into the evaluation of water quality. Therefore, the combined weight fuzzy mathematical method is more easily accepted and more persuasive.
