甘肃定西地区地质灾害危险性评价
为此,本文以甘肃定西地区为研究区,基于确定系数与逻辑回归耦合模型,分析地质灾害的空间分布特征及驱动因素,利用空间自相关分析探讨在不同尺度下地质灾害的空间聚集特征,以期为区域地质灾害监测与防治提供科学依据。 甘肃省定西地区位于青藏高原东北缘、黄土高原和西秦岭交汇地带。 研究区断裂构造发育,新构造活动强烈,特别是地震活动频繁,地表岩土体类型复杂,构造活动造成岩体破碎,新近系- 第四系固结-半固结,甚至为固结的地层发育,地壳隆升和河流侵蚀造成许多沟壑,斜坡上表层黄土分布广泛,地质灾害多发。 同时,人类工程活动对环境的破坏和气候变化等因素影响加剧了地质灾害(图1)。 近年来,受极端天气、地震和人类活动等多重因素叠加的影响,定西地区地质灾害发生频率明显上升。
