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