泥石流沟谷演化的不等时距灰色预测模型


1)泥石流沟谷纵剖面形态:
在条件均一、构造典型下的河谷纵剖面方程:
                

式中,h,l分别为河谷中某点距河口的高差。河长;h0L分别为流域高差河河流全场;N为纵剖面形态指数。
2)N值的不等时距灰色预测方法:


设原始列数为:x0)k),k=1,2,…,n且x0)k)与x0)k-1)之间的时距为T(k)-T(k-1)。
原始数据的一次累加式:
k=1时:


         x1)k)=x0)k)


k≥2时:
          

 

据此做GM(1,1)预测,得预测得累加量,再按式计算预测值。

     修正后的预测式:
