| 摘 要： | 根据集对分析理论,运用熵权法确定评价指标的权重值,采用简化改进后的联系度的确定方法,对土默特左旗平原区浅层地下水质量进行了评价。研究结果表明:土默特左旗平原区浅层地下水总体质量中等偏上,但对于已受到污染及处于中等程度的水质需要及时采取措施。与模糊综合评价方法相比较,该方法评判结果更能真实反映研究对象的状况,评价结果合理、客观。

| Abstract: | This research appraised the water quality of Tumd Left Banner according to the theory of set pair analysis method,the weights of evaluation indexes determined by using Entropy Weight and the determination method of connection degree by simplified improvement.The result proves that the environmental quality is above the average,but for those water that have already contaminated or moderate must take measures in time.The result of this model is reasonable and highly precise,which can reflect the actual condition of study objects through the comparison with comprehensive index method. |
