| 摘 要： | 科学全面地评价地下水水质质量,不仅有利于地下水资源保护,还可预防、控制或解决地下水开发利用造成的问题。根据博弈论的组合赋权思想对物元可拓模型进行改进,结合地下水质量标准建立了地下水质量综合评价模型。为验证改进模型的有效性,选取德阳市孝新合地区平水期7个点的地下水水质监测数据,用物元可拓法确定待评物元,计算各物元的关联系数,再采用组合赋权法综合优化变异系数法和污染贡献率法算得的权重,得到评价指标体系的综合权重,进而计算综合关联度,并据此确定各待评物元的水质等级。该模型评价结果与F值法、模糊数学法的评价结果对比分析表明,改进的物元可拓模型不仅能客观合理地反映地下水水质质量,还可预测水质变化趋势,较另外2种方法更合理可靠。

| Abstract: | Assessing the groundwater quality accurately is of great importance to protect groundwater resources and manage water issues caused by irrational utilization. Game theory is used to modify the matter-element extension assessment method based on standard groundwater quality classification. 7 observed groundwater data (located at Xiaoxinhe region, Deyang City) are used to verify the efficiency of the modified method. Firstly, incidence coefficients are calculated based on the matter-element theory. Then, game theory is introduced to integrate two different weights so that the integration weight values of each eigenvalue can be obtained. Ultimately, the groundwater quality classification of each groundwater sample is defined by using the maximum incidence coefficients. The assessed classifications of the samples not only agree well with the groundwater quality reality, but also can be used to predict the trend of the future groundwater quality. The assessment result is compared with results obtained by F value method and fuzzy mathematics method, and it shows the reasonableness and effectiveness of the modified model. |
