摘要: 运用信息熵理论,对川I藏公路德达一波戈溪沿线沟谷进行分析。结果表明:该沿线87.23%的沟谷处于幼年 和壮年期发育阶段,在一定的暴雨强度下易爆发泥石流;通过计算得到该方法对流域面积小于2km,高差低于1 km沟谷发育阶段的判断具有一定的准确性和客观性;同时,运用地貌信息熵理论也能客观的说明在一定区域内地 貌系统的演化过程不具有一致性

关键词: 信息熵, 沟谷危险性, 泥石流沟, 川藏公路

Abstract: Gullies along the Deda-Bogexi of Sichuan-Tibet Highway are analyzed by using the information entropy theory. The results shoWthat 87.23% of gullies are in the period of childhood and adolescent.which can easily occur debris floWin certain intensity storm.This method can be used to judge the growing period of gullies whose drainage area less than 2km and elevation less than 1 kMwith a certain degree of accuracy and objectivity.At the same time,it can prove that the evolu- lion process of landscape systeMdoesn’t have consistency in the same region by using information entropy.

Key words: information entropy, gully risk, debris floWgully, Sichuan-Tibet highway
