| 摘 要： | 在简述信息熵概念的基础上,对陕西潼关金矿区8条泥石流沟堆积的采矿废石量、沟谷纵坡降比等9个定量、定性调查指标进行了统计,求出各指标熵Hj、熵权Wj以及沟谷指标可能的概率值fij后,计算得出了潼关金矿区矿渣型泥石流潜势度信息熵的综合评价值;探讨了熵权评价与主观赋权评价的结果差异的原因及建议.

| Abstract: | On the basis of summarizing conceptions about the information entropy,the paper first works out all indexes of entropy,entropy weights and certain index and its corresponding probability f_(ij) in the light of 9 quantificational and qualitative research and statistical indexes,for example general quantity of slag,gradient ratio of 8 slag mudslide valleys in Tongguan gold mine area.Then,it presents the assessment of all-around value on the potentiality parameter.Lastly,it discusses the main affecting factors for the results about the entropy weights and subjective weight. |
