| 摘 要： | 甘肃省地质环境脆弱，地质灾害频发，是我国地质灾害最为严重的省份之一。面对如此严峻的地质灾害防灾形势，地质灾害风险评价已成为热门学科，是防灾减灾的一项有力的非工程措施。针对区域地质灾害风险评价方法和理论研究较多，形成了较为系统的技术流程，而对于单体地质灾害风险评价的研究相对较少。本次以宕昌县城关镇而信滑坡为例，利用已有单体地质灾害风险评价理论体系，阐述了大比例尺下的单体滑坡灾害的风险评价过程，得出了相应受险区的风险等级。

| Abstract: | Gansu Province is one of the most serious provinces with fragile geological environment and frequent geological disasters. Faced with such a severe situation of geological disaster prevention, geological disaster risk assessment has become a hot subject and a powerful non-engineering measure for disaster prevention and reduction. In view of the regional geological disaster risk assessment method and the theory research are many, has formed the quite system technical flow, but to the monomer geological disaster risk assessment research is relatively few. Taking the Erxin landslide in Chengguan town of Tanchang county as an example, this paper expounds the risk assessment process of large-scale single landslide disaster by using the existing theoretical system of single geological disaster risk assessment, and obtains the risk grade of the corresponding hazard area. |
