LANDSLIDE POTENTIALITY OF THE TSENGWEN RESERVOIR WATERSHED,TAIWAN,CHINA

To recognize the geographical characteristics of the landslide areas will be helpful for the watershed management in the reservoir watershed.According to the quantitative analysis,we'll take different scores and weighting for the potential parameters of the landslide areas in the Tsengwen reservoir watershed,and in the meanwhile,we'll extract the different factors,including the slope,aspect,altitude,soil and geological textures etc.,and the results shown as maximum one-day rainfall,ratio of forests and average relief is the most affecting parameters on the potential risk map of landslide areas.
