Abstract:
Qixia City is one of the regions where geological disasters such as landslide, and mudflow occur frequently. The formation of mudflow is mainly controlled by geographical environment, geological condition and human being economic ac- tivities. Basing on the geological disaster data, the development frequency, area consistency and scale of debris flow are clas- sified, and the method of distributing ratio is used to estimate mudflow. The high-dangerous zone, midst-dangerous zone and low dangerous zone are ensured, which provide a scientific bases for preventing rock-flow.
