摘要
采用灰色系统理论的关联度分析方法，研究了涪江上游滑坡的主要形成条件及触发因素。结果显示，相对高差是滑坡的主要形成条件；地震是滑坡的主要触发因素。此外，还对滑坡相关因素进行了相关显著性比较，评价了每项相关因素在其中所起的作用。最后讨论了灰色系统理论的关联度分析方法在滑坡研究中的利弊。
The main formation condition and main trigger factor of landslides over the upperreaches of the Fujiang River were studied by the method Of relation degree analysis of GreySystem Theory.The result shows that relation height of slope is the main formationcondition for landslides:r_5(relation height of slope)0.835>r_3(limerock stratum)0.832>r_4(slate stratum)0.826;earthquake is the main factor triggering of landslides:r_6(earthquake)0.891>r_7(rain)0.886>r_8(scour of the river)0.862>r_9(man-made)0.680.In addition,eachrelative factor of landslides was contrasted with realtive degree level,and effects on landslidesare evaluated.
