Abstract：A method investigating the geological background of debris flows along the famous disaster making rivers-the Dong River and the Xi River in Southwest China is briefly introduced in this paper. Based on the elevation data collected from the remote sensing images directly by means of a analytical plotter, a digital terrain model is established first, then followed by visual interpretation quantitatively and semi-quantitatively of a series of factors of geological environment, such as the characteristics of river-system, the drainage geomorphology,.the strata and rocks characters, the vegetation coverage and the disastreous geological phenomena etc.. Some useful conclusions and suggestions are made in this paper.
