2019年京津冀1：5万山区泥石流灾害隐患点数据

京津冀地区共调查确认泥石流灾害1841处，主要分布在太行山、燕山中低山地区，规模以小型和中型为主。泥石流灾害是本区最具破坏性的灾害类型，威胁人口和威胁财产最为严重。除受地质、地貌、构造、岩性以及降雨等因素外，人类不合理活动也在一定程度上加剧了滑坡灾害产生的几率和危害程度。A total of 1,841 debris flow disasters have been investigated and confirmed in the Beijing-Tianjin-Hebei region. These disasters are predominantly distributed in the mid-low mountainous areas of the Taihang Mountains and Yan Mountains, and are mostly small and medium in scale. Debris flow disasters represent the most destructive hazard type in this region, posing the most severe threats to both local populations and property. In addition to being influenced by factors including geology, geomorphology, tectonics, lithology and rainfall, unreasonable human activities have also exacerbated both the occurrence probability and hazard severity of landslide disasters to a certain extent.
