| 摘 要： | 水体富营养化已严重威胁到水安全及生态文明健康，故准确评价水体富营养化程度具有十分重要的意义，但水体富营养化程度评价受诸多模糊、随机因素的影响，具有不确定性，且尚无统一标准，是一个复杂不确定性问题。为有效刻画水体富营养化评价指标有限区间内的随机模糊性与考虑评价指标本身重要性及内在信息，探讨了耦合博弈论的水体富营养化状态的综合联系云评价模型。实例应用与对比分析表明，基于综合联系云的评价模型应用于水体富营养化评价是有效可行的，并具有计算简便和能综合考虑指标间相互作用的优点，应用博弈论确定的组合权重也能充分发挥评价指标的重要性和实测指标包含的客观信息，较只采用单一类型权重的云模型和其他评价方法的评价效果更好，为水体富营养化评价提供了一种新的参考。

| Abstract: | Water eutrophication has seriously threatened water security and ecological civilization health, so the rational evaluation of water eutrophication is of great significance. However, the evaluation of water eutrophication degree involving many fuzzy and random factors has no unified standard and it is a complex and uncertain problem. In order to consider the stochastic fuzziness, the importance and internal information of the evaluation index in the finite interval, a comprehensive connection cloud model based on the game theory was discussed here to evaluate the water eutrophication. Case study and comparisons with the cloud model only using a single type weight and other methods showed that the proposed model was effective and feasible for the evaluation of water eutrophication, and could consider the interaction, the importance and objective information of the evaluation index. It provided a new reference for the water eutrophication evaluation. |
