摘要:
以都汶公路左右5 km为研究区，引入森林立地类型划分方法，根据研究区的实际情况，把研究区划分为6类立地类型组，其中低海拔阳坡有176.11 km2、低海拔阴坡有156.89 km2、中海拔阳坡有174.76 km2、中海拔阴坡有174.80 km2、高海拔阳坡有41.59 km2、高海拔阴坡有39.35 km2，并分析了各地层岩性在各类立地类型组的分布关系；然后利用敏感性系数SC，分析了研究区内崩塌滑坡对地层岩性的敏感性，根据区域实际情况将敏感性系数划分为4个等级，其中极敏感区占研究区的29.39%、较敏感区占24.57%、较不敏感区占19.62%、极不敏感区占26.42%。
Abstract:
Taking Dou-wen Highway about five kilometers as research area, introducing the method of woods site type classification, according to research area actual situation, the research area is divided into six kinds of site types groups: low elevation sunny slope(176.11 km2),low elevation shady slope(156.89 km2),middle elevation sunny slope(174.76 km2),middle elevation shady slope(174.80 km2),high elevation sunny slope(41.59 km2),high elevation shady slope(39.35 km2), and analyzed the relationships between site type groups and stratum lithology. Then using sensitivity coefficient analyzed the sensitivity of collapse and landslide to stratum lithology in research area, according to research area actual situation, the sensitivity coefficient is divided into four ranks which extremely sensitive area accounts for 29.39% of the area of research area,slightly sensitive area accounts for 24.57%, slightly insensitive area accounts for 19.62%,extremely insensitive area accounts for 26.42% of the area of research area respectively.
