Detailed Description

泥石流沟综合评判的数学基础

(1)河沟的评判总得分N模型:

             N=A+B+C

             A=

               B=

               C=

               J=1,2,3,4

式中,A为地貌因素得分;B为河沟因素得分;C为地质因素得分;i为各因素项目;j为类目。

(2)综合评判别条件模型:

     严重:NN1

     中等:N1>N≥N2

     轻微:N2>N≥N3

     没有:N3>N

式中,

      N1=ai1+bi1+ci1+ai2+bi2+ci2),

      N2=[(ai2+bi2+ci2+(ai3+bi3+ci3],

      N3=[(ai3+bi3+ci3+(ai4+bi4+ci4],
