摘要
应用吉林省某地区8条泥石流沟资料,以主沟坡度、单位流域面积松散物源量、山坡坡度、流域切割密度、植被覆盖率、补给段长度六项为评价因子,采用BP神经网络的方法对文中的泥石流沟进行评价,发现BP神经网络的方法对研究泥石流危险度是合理并且相对简单的。
This paper used 8 debris flow catchments as examples, the gradient of the main channel, loose material volume per area, slope gradient, ravine density, vegetation coverage, supply ratio were selected as influencing factors. BP neural network was used for the debris flow evaluation. It is drawn that BP neural network theory is simple and rational to study the debris flow hazards.
