摘　　要：以安徽省当涂县地质灾害为基础依据,对县域内崩塌、滑坡和地面塌陷36处地质灾害隐患点的分布特征和主控因素进行分析研究。研究结果表明,在空间分布上,中北部丘陵区发育程度集中,主要与地层岩性、地形地貌、地质构造和人类工程活动等多种因素有关;在时间分布上,当涂县地质灾害主要集中在降雨季节,特别是3—7月,为研究区地质灾害的高发期。研究结果不仅可以更好地了解当涂县地质灾害的分布情况和主控因素,为防灾减灾提供科学依据,同时也可以为土地利用规划、城市建设等领域提供技术支持。Based on the geological hazards in Dangtu County,Anhui Province,the distribution char⁃acteristics and main controlling factors of 36 geological hazards in the county are analyzed.The results show that the development degree of the hilly area in the central and northern part is concentrated,which is main⁃ly related to many factors such as stratigraphic lithology,landform,geological structure and human engi⁃neering activities.In terms of time distribution,geological disasters in Dangtu County are mainly concentrat⁃ed in the rainfall season,especially from March to July,which is the high occurrence period of geological di⁃sasters in the study area.The research results can not only better understand the distribution and main con⁃trol factors of geological disasters in Dangtu County,provide scientific basis for disaster prevention and re⁃duction,but also provide technical support for land use planning,urban construction and other fields.
