Abstract In this paper, we presented a restorative vegetation map according to the geographic position of the region, the rules of vegetation distribution along an altitude gradient, and so on. In addition, texture feature images and ancillary data including the topographic map, the documentary data and the field sampling data were collected and used for improving classification.
     The result of vegetation mapping showed that the restorative vegetation are categorized evergreen broad-leaved forest (under 900 m), evergreen and deciduous broad-leaved mixed forest (from 900 to 1600 m) and deciduous broad-leaved forest (from 1600 to 2200 m) respectively; The total forest area of Longmenhe region is about 4419.2 hm2, occupying 93.71% of the total area. In the vegetation map, 65 formations under eight vegetation types were classified. Among these vegetation types, the evergreen and deciduous broad-leaved mixed forest covered the largest area. Its area was 1674.09 hm2, occupying 37.88% in terms of area. In addition, the area of both orchard and farmland covered 228.12 hm2, accounting for 4.84% of this region.

     From the overlaid restorative vegetation map with the formation map and further analysis, coniferous forest, coniferous and deciduous broad-leaved mixed forest, shrubbery and meadow appear in this region as a result of human disturbance. The area of four vegetation types is about 34.6% . Coniferous and deciduous broad-leaved mixed forest is the dominant type in this area.
