Abstract:: Yikeyin valley is located in Li County of northwest Sichuan province, which has the typical characteristics of debris flow, and had historically broken out large-scale debris flow. ‘5·12’ Wenchuan earthquake induced a mass of secondary mountainous disasters such as collapse, landslide and at the same time lead to appear a number of jams in the circulation area, we preliminary estimated that will make the debris flow ravines be active in 10~20 years after earthquake. Through field study and remote sensing image data,we obtained the basic characteristics of the valley basin before and after the earthquake, then compared with the source on the distribution and stability in the valley before and after the earthquake,we made a series of conclusion,such as: unstable source increases,and also because of Jam activity intensity increases, peak flow increase exponentially after the earthquake, on this basis we could got a reasonable evaluation of the development trend of the debris flow after the earthquake, additionally in the post-disaster reconstruction process, which could provide the reference for the debris flow in predicting, forecasting and prevention and control work.
