2019年京津冀1：5万山区崩塌灾害隐患点数据

京津冀地区共调查确认崩塌灾害956处，主要分布在太行山、燕山中低山地区，如图5-26所示。崩塌灾害会造成人员伤亡，破坏工程设施，威胁交通安全，阻碍山区经济发展。本区崩塌灾害除受地质、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地质灾害产生的几率和危害程度。

A total of 956 collapse disasters have been investigated and confirmed in the Beijing-Tianjin-Hebei region, predominantly distributed in the middle and low mountainous areas of the Taihang Mountains and Yan Mountains, as illustrated in Figure 5-26. Collapse disasters may cause casualties, damage engineering facilities, threaten traffic safety, and impede economic development in mountainous areas. Apart from being affected by factors including geology, topography, structure, lithology and rainfall, unreasonable human activities have also exacerbated the occurrence probability and hazard severity of geological disasters in this region to a certain extent.
