| 摘要: |
| 将待评价样本作为事件, 水质级别作为对策, 构造局势.通过用效果测度统－计量评价指标, 按级别变量特征值确定最优局势, 提出了用改性灰色局势决策法综合评价湖泊水体富营养化状况并结合实例说明该决策法评价湖泊水体富营养化, 具有客观性和实用性. |

| Abstract: |
| This paper studies the practicability and rationality of the application of grey system theory to the assessment of water quality of lakes and proposes the multi-target grey situation decision making method by using grey decision theory.Here, the water sample is taken as an event, the grade of water quality as a strategy, then a situation is set up.By using effect measure to unify the indexes with the grey situation decision making and determining the optimum situation according to the eigenvalues of grade variables, a new method is presented for evaluating eutrophication in lakes.The assessment result of nine lakes' eurtophication shows that it's practicable to assess eutrophication of lakes by using I his method. |
| Key words: Grey situation decision making effect measure weight eutrophication evaluation |
