摘要
Based on the theory of hazard-prone area division,seven evaluation indexes such as quantity of hazard points, topography and geomorphology, geological structure, rock and soil mass type, multi-year average precipitation, vegetation coverage ratio and human engineering activities were put forward. A model of geological-hazard-prone area division named optimal systems weighting law was proposed. The result shows that the division of geological-hazard-prone area of Jilin Province coincides with the practical situation.
