摘要
地质灾害危险性是地质灾害发育密度、活动规模、活动频次的综合性反映。从这一认识出发,本文论述了地质灾害危险性构成及其评价方法,在此基础上,以县(市、区、旗)和省(直辖市、自治区)为单元,进行了崩塌、滑坡、泥石流灾害危险性评价与区划,分析了危险性分布情况与区域变化规律。
The danger level of geological hazards is a comprehensive reflection of the density of occurrence, extent of activity and frequency of occurrence of geological hazards. From this view, this paper discusses the structure of danger of geological hazards and method of its assessment. On that basis, the dangerous assessment and divisions of collapses, landslide and debris flows of geological hazards are made with counties (cities,districts and banners)and provinces (municipalities directly under the Central Government and autonomous regions)as the units, and the dangerous distribution and the law of regional changes of geological hazards are analyzed.
