摘要
【目的】进一步厘清鄠邑区地质灾害隐患底数和灾害发育趋势,提升地质灾害防治能力。【方法】通过1∶5万地质灾害风险评价工作,开展野外调查和钻探工作,查明区域内地质灾害类型和形成机理,总结地质灾害分布规律。【结果】根据斜坡单元划分地质灾害风险区,建立地质灾害调查空间数据库,得出鄠邑区地质灾害风险区划图,共划分出34个分区,其中地质灾害极高风险区11个、高风险区17个、中风险区3个、低风险区3个。【结论】应加强地质灾害风险区管理,在编制国土空间规划时,充分考虑地质灾害极高、高风险区因素,严格进行用途管制。
[Purposes]This study aims to further investigate the geological hazards and their development trends in Huyi District,and enhance the ability to prevent and control geological disasters.[Methods]Through 1∶50,000 geological hazard risk assessment,field investigation and drilling were conducted to identify the types and formation mechanism of geological hazards in the region,and the distribution pat⁃tem of geological hazards was summarized.[Findings]According to the slope unit,the geological hazard risk area is classified into 34 zones,and the geological hazard investigation spatial database is estab⁃lished,among them,there are 11 extremely high risk areas,17 high risk areas,3 medium risk areas and 3 low risk areas.[Conclusions]Strengthen the management of geological hazard risk areas,fully consider the factors of extremely high geological hazard and high-risk areas in the preparation of national spatial planning,and strictly regulate land use.
