Zoning of Geological Hazards’Susceptibility Evaluation in Suide County of Shaanxi Province
摘要
Abstract
Based on investigation of geohazards in Suide County,density of geohazards,slope height,gradi-ent,slope type,type of rock and earth mass,rainy water and human activities are chosen as 7 evaluation index to establish susceptibility evaluation index system.The study area is finally divided into 3 levels of the high-grade area by using the information content method on the GIS platform.According to the results,the high-grade area covers 326.04 km2 ,accounting for 17.4% of the total area;the medium-grade area covers 1 349.8 km2 ,accounting for 71.9% of the whole area and the low-grade area is 202.16 km2,accounting for 10.7%.It hopes to provide some technology support to prevent and reduce geohazards by zoning of geological hazards’susceptibility evaluation in Suide County.关键词
