Abstract: As the state attaches great importance to the prevention of geological disasters, the investment of geological disasters prevention has been increasing year by year.Evaluating the investment effect of geological disaster prevention can provide scientific basis for the effective geological disaster prevention work.Based on the analysis of the current situation from 2008 to 2018,we evaluated the efficiency of geological disaster prevention in Shaanxi Province by DEA-BC2 model.Through the analysis of the comprehensive efficiency value, technical effectiveness and scaled return, we proposed several effective measures for the prevention of geological disasters by the analytic hierarchy process.The results showed that the year of 2008,2011 and 2012 were at the forefront of comprehensive efficiency, indicating that the investment in geological disaster prevention had achieved better results.In other years, the input-output structure of local disaster prevention and control was poor, and it needed to further improve the input scale or improve the technical level.In terms of prevention measures, it demonstrated that geological disaster monitoring and early warning, weather early warning, effective supervision of engineering activities and geological disaster investigation were effective measures to raise the level of geological disaster prevention in Shaanxi Province.The research results can provide reference to strengthen the geological disasters prevention in the future.
