长期以来对于地质灾害危险性评价都是定性分析的。本文在深入的学习了以前的工作者的研究成果的基础上，结合实际问题，运用模糊评价法以及灰色聚类法两种不同的方法建立了数学模型对吉林省磐石市地质灾害危险性进行了定量化评价。%For a long time, the geological disaster risk assessment is qualitative. Based on the in-depth study on the research achievements of previous workers, combined with the practical problems, the paper uses fuzzy evaluation method and grey clustering method to establish the mathematical model to carry on the quantitative evaluation for geological disaster risk in Jilin Panshi.
