| 摘 要： | 鉴于水质评价指标的多样性和由单指标给出评价结果的不相容性,从物元分析和可拓集合的理论出发,建立了基于物元可拓法的地下水水质评价模型,以梨树县平原区浅层地下水为研究对象,进行了水质综合评价。综合关联度和可拓指数的计算结果表明,东辽河沿岸的孤家子、东河以及金山一带水质已遭受污染,局部地区水质有从Ⅱ级向Ⅲ级转化的趋势。通过与综合评分法的评价结果对比,验证了该评价模型的可靠性,它不仅可以客观地反映地下水水质总体状况,而且可定性地分析样本水质的变化方向,使评价结果更接近于实际情况。 |

| Abstract: | In view of the diversity of the water quality evaluation and incompatibility of evaluating results given by single index,the authors establish the groundwater quality evaluation model using the matter-element and extension method.As an example,the authors conduct a comprehensive evaluation of groundwater quality to the shallow groundwater in Lishu plain areas.Through the calculation of the integrated degree of association and extension index,the results show that the groundwater has been polluted along the ... |
