APPLICATION OF FUZZY COMPREHENSIVE EVALUATION IN THE GRADING OF GEOLOGICAL HAZARD IN XINBIN COUNTY, LIAONING PROVINCE

With the study on the development of geologic hazards in Xinbin County, Liaoning Province, the natural and artificial factors that affect the happening and developing of geologic hazards in the area are analyzed. Applying fuzzy comprehensive evaluation method, the easy-happening degree of five types of geologic hazards, such as mudflow, collapse, landslide, ground breakdown and ground crack, are divided and assessed by grid splitting.
