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.
