烟台市地质灾害现状及易发程度分区评价

Present Condition of Geological Hazards and Susceptibility Zoning in Yantai City

摘要:

加强自然灾害防治关系到国计民生。烟台市域面积13864.5km2，截至2020年末共有崩塌、滑坡、泥石流、岩溶塌陷、采空塌陷5类共405处地质灾害隐患点，数量约占全省总数的1/5。本文基于2020年山东省烟台市地质灾害核查数据，总结了烟台市地质灾害发育现状及灾情损失。采用地质灾害综合危险性指数法，开展了烟台市易发程度分区评价，划分出了高、中、低及不易发区。结合烟台市国民经济和社会发展规划将全市地质灾害防治区划分为重点防治区、次重点防治区和一般防治区，针对不同分区提出了具体的防治工作建议，为烟台市地质灾害防治工作提供了基础依据。
