摘要
尼泊尔Ms8.1级地震触发西藏定日县次生灾害较严重,主要为泥石流、崩塌和不稳定斜坡。统计分析地震触发的次生地质灾害数量在各乡(镇)分布差异较大,且此次地震触发的次生地质灾害主要是中小型灾害,灾害类型主要为泥石流。基于次生地质灾害分布特征,将定日县灾害防治划分为重点防治区、次重点防治区和一般防治区。结合不同分区的灾害分布特点,提出了针对性的次生地质灾害防治措施,研究成果将有助于相关主管部门合理、高效、快捷的实现灾后重建及防灾减灾人力、物力和财力的合理使用。
Nepal Ms8.1 earthquake triggered serious secondary disasters in Dingri County,Tibet,China,including debris flow,collapse and unstable slope.Statistical analysis shows that the number of secondary geological disasters triggered by the earthquake is quite different in each township(town),and the secondary geological disasters triggered by the earthquake are mainly small and medium-sized disasters,and the main type of disaster is debris flow.Based on the distribution characteristics of secondary geological disasters,Dingri county is divided into key,secondary and general prevention and control area.Combined with the characteristics of disaster distribution in different areas,the paper puts forward the targeted prevention and control measures against secondary geological disasters.The research results will help the relevant departments to realize the reasonable,efficient and fast post-disaster reconstruction and the rational use of human,material and financial resources for disaster prevention and mitigation.
