摘　　要：泾源县位于陇东黄土高原西部,整体属于剥蚀侵蚀挤压型断块中山区。2021年10月,泾源县现有各类地质灾害隐患85处。诱因主要为地形地质条件复杂、地质构造发育、降水时空分布不均匀等自然条件的影响,加上矿山开采等人类活动带来的破坏作用。在此基础上,根据泾源县矿山地质灾害风险性评价结果将工作区划分为重点防治区、次重点防治区和一般防治区,并提出了不同分区的地质灾害风险管控措施建议。Jingyuan County is located in the west of Longdong Loess Plateau and belongs to the middle mountain area of denudation erosion compression fault block as a whole. In October 2021, there are 85 hidden dangers of various geological disasters in Jingyuan County. The inducements are mainly the influence of natural conditions such as complex topographic and geological conditions, development of geological structures, uneven temporal and spatial distribution of precipitation,and the destructive effect brought by human activities such as mining. On this basis, according to the risk evaluation results of mine geological disasters in Jingyuan County, the working area is divided into key prevention and control areas, sub key prevention and control areas and general prevention and control areas, and suggestions on geological disaster risk control measures in different areas are put forward.
