摘要
本文阐述利用灰色关联法进行了森林火灾危险性风险评价,讨论了风险评价的指标选取、数学模型(GM)和计算步骤,并结合具体事例计算了某林区的森林火灾危险性关联因子的关联度,关联序,关联矩阵和权重,以此为森林火灾预测危险程度提供了科学参考。
In this paper,gray correlation method was carried out to research the risk assessment in the forest fire,and then analysed the indexes determination,mathematical models(GM)and calculation steps for the risk assessment.The paper took a forest for example combined with the gray correlation method to get the correlation,correlation order,correlation matrix and weight as a scientific basis for the forecasting degree of risk for forest fire.
