基于灰色关联度法的雾灾损失评估模型研究

Study on fog disaster loss evaluation model based on grey relational analysis

摘要: 根据大雾灾害的实际情况和数据的可得性，选取了死亡人数、受伤人数、受灾面积、大雾持续时间和直接经济损失作为评价指标，运用灰色关联度法来建立雾灾损失评估模型，并进行实例分析。结果表明：运用灰色关联度方法建立的雾灾损失评估模型进行雾灾的灾害等级划分，是较为合理的，基本符合实际情况。

Abstract: Using the death toll, injured persons, covered disaster areas, heavy fog duration and direct economic loss as the evaluation indices, fog disaster loss evaluation model was established by grey relational analysis. The results indicate that the model is reasonable for fog disaster grade division.
