地貌相关分析公式

1)秦皇岛滨海区相邻两级阶地之高差的沿程变化:

  式中,为相邻两级阶地之高差(i=1,2,3),且=-=6.2+4.29S-0.594=-=3.2+3.02S-0.424,==3.3-0.911S+0.290;S为距出山口的距离;a,b,c为常数。

         2)各期累计抬升高度间的内在联系:

                     

         3)抬升梯度(抬升幅度随距离的变化率):

                     

 式中,为抬升梯度。

         4)海滩视宽度Bm)与海滩坡度α(°)的关系:

                

        5)海滩视宽度Bm)与海滩中潮位砂的中值粒径mm)之关系:

                

        6)流域面积Bk)与河长Lkm)间有良好正比直线关系:

                 F=11.23L-125
