本研究以建立之評估準則和體系，調查和評估大雪山地區之全區和道路、步道之地質環境敏感度及其分布。研究結果顯示本區地勢上緩下陡，坡度普遍陡峻而易崩塌，環境敏感度甚高，小面積緩坡地零散見於近山脊處。林道經過山腹，多處崩塌；登山步道則沿山脊而行，路況尚佳。從遊憩資源與環境敏感度言，本區不宜一般性遊憩活動。

　　　　　The present study is aimed at mapping and categorizing the geologically hazardous areas of the region as well as the forest roads and trails with established parameters and evaluation systems. The results thus obtained show that the region is generally high in sensitivity; areas with moderate sensitivity are sporadically distributed near the ridges where the slope is usually gentler than the other parts of the region. The mountaineering trails in the area concerned run along the ridges which are generally broad and gentle, and thus are not too bad in condition. Never-the-less, considering the accessibility and recreation resources, the study area is not suitable for tourism.
