| 摘 要： | 针对水资源短缺风险评价中各指标具有模糊性及应用单一模型评价存在的偏面性问题,采用可变模糊评价模型进行水资源短缺风险评价可提高评价结果的可靠性,并将熵权作为客观权重与主观权重相结合确定指标综合权重。实例应用结果表明,该模型计算简便,评价结果可靠、合理。

| Abstract: | Aiming at fuzziness of evaluation indicators in water resources shortage risk,as well as the problem of single one-sided issue due to evaluating with single model,variable fuzzy evaluation model is employed to evaluate water resources shortage risk in this paper,The model can be transformed into several models for evaluation by changing its parameters,which improves the reliability of evaluation results.For determining reasonable indicator weights,entropy theory is employed to calculate objective weights,an... |
