以地形坡度、地层岩性、到地质断层距离、到地面水体距离、土地利用类型和到交通干线距离为评价因子,应用信息量模型,对重庆市涪陵区进行地质灾害危险性评价。将涪陵区地质灾害危险性划分为极重度危险、重度危险、中度危险、轻度危险和无危险5个等级,涪陵区地质灾害危险区主要分布在长江和乌江沿岸带、黄草山和武陵山两山生态控制区以及境内人口密集的城镇建设区,中度以上危险区域主要分布在北部沿江新妙镇、石沱镇、珍溪镇;西南坪上的北部高山区;沿乌江江南城区和白涛片区以及武陵山的南部地区等,这些沿江、沿河区域由于复杂的地质构造、地形特征以及不良的人为活动,其地质灾害的危险性明显高于地势平坦地区。
The geohazard risk assessment of Fuling District of Chongqing City was carried out based on the topographic gradient, lithology of the formation, the distance to the geological fault, the distance to the surface water body, the type of land use and the distance to the traffic trunk line. The Fuling District, the risk of geological disasters can be divided into very serious danger, severe danger, moderate danger, mild danger and no danger five levels. The geological hazards in Fuling District are mainly distributed in the Yangtze River and Wujiang River, Huangcao Mountain and Wuling Mountain The two mountain ecological control areas and the densely populated urban construction areas in the country. The moderately-above dangerous areas are mainly distributed in Xin Miaozhen, Shituo Town and Zhenxi Town along the northern coast, northern high mountain areas on the southwest plateau, Tao area and the southern part of Wuling Mountain. Due to the complicated geological structure, topographical features and bad man-made activities, the risk of geological disasters in these riverside and riverine areas is obviously higher than that in the flat terrain.
