초록

Vertical forest distribution is one of the important factors to understand various ecological
mechanism such as succession, disturbance and environmental effects. LiDAR data provide
information, both the horizontal and vertical distribution of forest structure. The laser scanner
survey provided a point cloud, in which the x, y, and z coordinates of the points are known.
The objectives of this study were 1) to analyze factors of forest structure such as individual tree
isolation, tree height, canopy closure and tree density using LiDAR data and 2) to compare the
forest structure between outer and interior forest. The paper conducted to extract the individual
tree using watershed algorithm and to interpolate using the first return of LiDAR data for
yielding digital surface model (DSM). The results of the study show characters of edge such as
more isolated individual trees, higher density, lower canopy closure, and lower tree height than
those of interior forest. LiDAR data is to be useful for analyzing of forest structure. Further
study should be undertaken with species for more accurate results.
