【摘要】 针对地形复杂地区线路工程地质灾害监测难度大的问题,以甘肃省陇南市徽县至凤县路段为研究区,在分析地理、地形地貌、水文、植被等资料基础上,基于地理信息与遥感技术建立适宜的地质灾害评价指标体系。研究表明,研究区以地质灾害以中易发性为主,面积约120.291km~2,占总面积的30%;地质灾害低易发、不易发地区占总面积的54%,而高易发区面积约63.088km~2,占总面积的16%,主要集中在坡度陡、海拔高的地区。更多还原

【Abstract】 Aiming at the difficulty of monitoring engineering geological disasters in areas with complex terrain,the section from Huixian to Fengxian,Longnan City,Gansu Province is used as the research area.Based on the analysis of geography,topography,hydrology,vegetation and other data,it is based on geographic information and remote sensing.The technology has established a set of suitable geological disaster evaluation index system.Studies have shown that the study area is dominated by medium-prone geological hazards,covering an area of about 120.291 km~2,accounting for 30% of the total area;low-prone and low-prone areas of geological hazards account for 54% of the total area,while the high-prone area is about 63.088 km~2,accounting for 16% of the total area,mainly concentrated in areas with steep slopes and high altitudes.更多还原
