Geo-hazard Risk Evaluation in Huangling County Shaanxi Province
In order to design geo-hazard prevention and control planning better, according to a detailed investigation of geo-hazard information, the geological environment conditions and the characteristics of geo-hazard in Huangling County were detailed analyzed, the geo-hazard evaluation index were determined and quantified, the weights were gotten using a method combining the qualitative analysis with quantitative calculation, geo-hazard risk was evaluated in weighted sum method. The results show that the high-risk areas mainly distributed in Luohe River valley area, Juhe River valley area and Nanchuan River valley area. The area have great resident population, frequent movement of floating, fast urbanization and strong human engineering activities. The high-risk and middle-risk geo-hazards are widely developed. The risk evaluation result is consistent with the actual situation, and is credible.
