Characteristics And Risk Assessment Of Landslide Hazards In Bazhou District Of Bazhong City

This article is based on the East Sichuan Ba River Basin geological disaster survey conducted on the project, according to the basis of Bazhou natural geography, hydrology and meteorology, regional geological and environmental data collected in full, the actual point of the study area of landslide hazards survey, by natural and geographical conditions and geological environment background analysis of the study area, the condition of formation drawn landslides, development mechanism, distribution characteristics and influencing factors. It analyzes and summarizes landslide hazard evaluation principles, evaluation methods and evaluation procedures to finalize the use of Arc GIS software as a platform to achieve, respectively information and fuzzy comprehensive evaluation method of the study area landslide hazard assessment, to achieve Bazhou landslide hazard zoning.The results show that: Bazhou landslide hazard assessment is divided into high-risk areas, dangerous areas and low-risk areas, where the risk of information law to obtain zoning map, a high-risk area contains 70.2% of known landslide disaster point, fuzzy comprehensive evaluation method to obtain risk zoning map, the high risk of containing 53.7% of known landslide hazard points. The resulting two kinds of methods hazard zoning map are close to high-risk area is mainly distributed in the northeast and west of Bazhou region, the landscape is mainly distributed in the lower structure in Zhongshan, the first danger zone is mainly distributed in the southwest of Bazhou District landscape erosion gully erosion mainly in the low-lying land erosion and accumulation zone, which is the actual phase composite.
