地貌气候单位线模型及流路概率计算公式

       1)适合于地貌特性比较均一:

                

  式中,γ=k(α+1);α,β为参数;ht)为地貌气候单位线纵坐标;t为时间;s为某一具体流路;S为流域流路集合;Ps)为概率。

        2)适合于地貌不够均一:

                

  式中,参数同上。

        3)适合于地貌很不均一:

                  

   式中,0=(α+);=),…,=);

         =),…,=);

         M=-);N=(-)H=+2);为参数。

         4)流路概率的计算公式:

          1)初识概率的计算公式:

                  

           2)转移概率P公式:

                  

   式中,分别为合计面积权;N为河流数目;为所有可发生路径的支流数目,注脚中无逗号为连续,有逗号为间断。
