摘要
蓝田县是西安市辖县之一,境内河流众多,地质构造复杂,大断裂发育,岩土体结构类型复杂,人类活动强度地域差异大,降水量大且集中,地质灾害发育。目前共有地质灾害201处,其中滑坡93处,崩塌106处,泥石流2处。受地形地貌、地质构造、地层和岩土体结构等因素的影响,在降雨和人类工程活动的双重作用下,地质灾害类型和时间—空间分布规律存在显著的地域性特点。
Lantian County is one of the counties under the jurisdiction of Xi＇an City. In the county there are many rivers, the geologi- cal structure is complex with major faults, rock and soil structure type is diverse, the human activities is strong and large diversity in different areas; the rainfall is large and concentrated, the geological hazard is development. At present, there are 201 geological disasters, including 93 landslides, 106 collapses, 2 debris flows. Influenced by topography and geomorphology, geological structure, strata and rock mass structure, under the dual function of rainfall and unreasonable human engineering activities, the geological disaster type and time-space distribution have significant regional characteristics.
