在灰色关联度的基础上，以定义的关联差异度为测区，并结合级别变量特征值，构造了一种新的灰色模式识别理论模型.以云南昭通地区11县（市）滑坡、泥石流危险度评判为例介绍了该模型的计算步骤，并与其它方法比较表明该模型能够更精确地反映危险度客观实际． Based on the gray relational degree, a new gray pattern recognition theoretical model was constructed based on the defined correlation degree of variance and the eigenvalues ​​of the level variables. The landslides, landslides and debris flows in 11 counties (cities) in Zhaotong, Yunnan Province Degree evaluation as an example, the calculation steps of the model are introduced and compared with other methods to show that the model can more accurately reflect the objective reality of the degree of risk.
