重庆是我国面积最大的直辖市,境内江河纵横,群山叠嶂,地势由南北向长江河谷逐渐降低,西北部和中部以丘陵、低山为主,中山为辅,东南部位于大巴山区和武陵山区内。从地质学上讲,重庆位于龙门山、大巴山和扬子地台等几个构造单位之间,在多种复杂地质环境的长期影响下,渐渐形成了如今的多山多谷地貌。独特的地质构造成就了山城重庆旖旎的自然风光,同时也为地质灾害埋下了隐患,岩石崩塌、滑坡、泥石流、地震、地裂缝和地面塌陷等均在重庆出现过,因此地质灾害防治工作在重庆一直备受重视,政府部门常年开展地质灾害的调查工作。
Chongqing is the largest municipality directly under the Central Government in China. Its territory is dominated by rivers and mountains. Its terrain is gradually reduced from north to south to the Yangtze River valley. Its northwestern and central parts are mainly hilly and low mountains, supplemented by Zhongshan, and southeastern Dabashan and Wuling Mountains . Geologically speaking, Chongqing is located between Longmen Mountain, Dabashan and Yangtze Platform and other structural units. Under the long-term influence of many complex geological environments, the mountainous and multi-valley landscapes are gradually formed. The unique geological structure has made the mountain city of Chongqing an exquisite natural scenery, meanwhile it also buried hidden dangers for geological disasters. Rock avalanches, landslides, debris flows, earthquakes, ground fissures and ground subsidence all occurred in Chongqing. Therefore, Chongqing has always been valued by government departments for carrying out geological disasters investigations.
