【摘要】 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．更多还原

【Abstract】 In this paper, based on the grey relational degree and relational discrepency degree, by combining with eigenvalue of grade variable, a new model of greymode identification is established. As an example,the method and steps of the evaluation for the landslide and debris flow risk degree in zhaotong district are introduced. The comparison with other methods shows that this model is rationality and utility for the disasterevalua t ion.更多还原
